About the end of the seventh year of the hijrah, the Quraish and their allies, the Bani Bakr, violated the terms of the peace concluded at Hudaibiya by attacking the Bani Khuzaah, who were in alliance with the Muslims. The Bani Khuzzah appealed to the Prophet for help and protection. The Prophet determined to make a stop to the reign of injustice and oppression, which had lasted so long at Mecca. He immediately gathered ten thousand men to march against the idolaters and set out on January, 630.
After eight days the Muslims army halted, and alighted at Marr Az-Zahran, a day's journey from Mecca. On the night of their arrival, Abu Sufyan, who was delegated by the Quraish to ask the Prophet to abandon his project, presented himself and besought an interview. In the morning it was granted. "Has the time not come, O Abu Sufyan," said the Prophet, "for you to acknowledge that there is no deity save Allah and that I am His Messenger?" Abu Sufyan, after hesitating for awhile, pronounced the prescribed formula of belief and adopted Islam. He was then sent back to prepare the city for the Prophet's approach.
With the exception of a slight resistance by certain clans headed by Ikrima and Safwan, in which many Muslims were killed, the Prophet entered Mecca almost unopposed. The city which had treated him so cruelly, driven him and his faithful band for refuge among strangers, the city which had sworn his life and the lives of his devoted adherents, now lay at his mercy. His old persecutors were now completely at his feet. The Prophet entered Mecca on his favorite camel Al Kaswa, having Usama Ibn Zaid sitting behind him. On his way he recited Surah Al Fath (Victory), the first verses of which maybe interpreted thus: Verily! We have given you (O Muhammad) a manifest victory. That Allah may forgive you your sins of the past and future, and complete His Favor on you, and guide you on the Straight Path; and that Allah may help you with strong help. (Ch 48:1-3 Quran)
The Muslim army entered the city unpretentiously and peacefully. No house was robbed, no man or woman was insulted. The Prophet granted a general amnesty to the entire population of Mecca. Only four criminals, whom justice condemned, were proscribed. He did however, order the destruction of all idols and pagan images of worship, upon which three hundred and fifty idols which were in the Sacred House of Ka'ba were thrown down. The Prophet himself destroyed a wooden pigeon hung from the roof and regarded as one of the deities of the Quraish. During the downfall of the images and idols he was heard to cry aloud: "Allah is great. Truth has come and falsehood has vanished; verily falsehood is fleeting." The old idolaters observed thoughtfully the destruction of their gods, which were utterly powerless. After the Prophet had abolished these pagan idols and every pagan rite, he delivered a sermon to the assembled people. He dwelt upon the natural brotherhood of man in the words of the Qur'an: O Mankind! We have created you for a male and a female, and made you into nations and tribes, that you may know one another. Verily, the most honorable of you in the Sight of Allah is that (believer) who has At-Taqwa (one of the Muttaqun, pious, and righteous persons who fear Allah much, abstain from all kinds of sins and evil deeds which He has forbidden), and love Allah much (perform all kinds of good deeds which He has ordained.) Verily Allah is All-Knowing, All-Aware. (Ch 49:13 Quran)
Narrated Hisham's father: When Allah's Messenger set out (towards Mecca) during the year of the Conquest (of Mecca) and this news reached (the infidels of Quraish), Abu Sufyan, Hakim Ibn Hizam and Budail Ibn Waraqa came out to gather information about Allah's Messenger. They proceeded on their way till they reached a place called Marr-az-Zahran (which is near Mecca). Behold! There they saw many fires as if they were the fires of Arafat." Budail Ibn Waraqa' said: "Banu' Amr are less in number than that." Some of the guards of Allah's Messenger saw them and took them over, caught them, and bthem to Allah's Messenger. Abu Sufyan embraced Islam.
When the Prophet proceeded, he said to Al' Abbas: "Keep Abu Sufyan standing at the top of the mountain so that he would look at the Muslims. SO Al- Abbas kept him standing (at that place) and the tribes with the Prophet started passing in front of Abu Sufyan in military batches. A batch passed in front of Abu Sufyan and said: "O 'Abbas who are these?" 'Abbas said: "They are Banu Ghaifar." Abu Sufyan said: "I have got nothing to do with Ghifar." Then a batch of the tribe of Juhaina passed by and he said similarly as above. Then a batch of the tribe of Sa'd Ibn Huzaim passed by and he said similarly as above. Then came a batch, the like of which Abu Sufyan had not seen. He said: "Who are these?" Abbas said: "They are the Ansar headed by Sa'd Ibn 'Ubada, the one holding the flag." Sa'd Ibn 'Ubada said: "O Abu Sufyan! Today is the day of a great battle and today (what is prohibited in )the Ka'ba will be permissible." Abu Sufyan said, "O Abbas! How excellent the day of destruction is!" Then came another batch of warriors which was the smallest of all the batches, and in it there was Allah's Messenger and his companions, and the flag of the Prophet was carried by Az-Zubair Ibn Al-Awwam. When Allah's Messenger passed by Abu Sufyan, the latter said to the Prophet: "Do you know what Sa'd Ibn Ubada said?" The Prophet said: "What did he say?" Abu Sufyan said: "He said so-and-so." The Prophet said: "Sa'd told a lie, but today Allah will give superiority to the Ka'ba and today the Ka'ba will be covered with a cloth covering." Allah's Messenger ordered that his flag be fixed at Al-Hajun.
Narrated Urwa: Nafi' Ibn Jubair Ibn Mut'im said: "I heard Al-Abbas saying to Az-Zubair Ibn Al- Awwam, 'O Abu Abdullah! Did Allah's Messenger order you to fix the flag here?' "Allah's Messenger ordered Khalid Ibn Al-Walid to enter Mecca from its upper part from Kadaa' while the Prophet himself entered from Kudaa. Two men from the cavalry of Khalid Ibn Al-Walid named Hubaish Ibn Al Ashar and Kurz Ibn Jabir Al-Fihri were martyred on that day. (Sahih Al Bukhari)
Now great multitudes came to adopt Islam and take the oath of allegiance to the Prophet. For this purpose an assembly was held at As-Safa Mountain. Umar, acting as the Prophet's deputy administered the oath, whereby the people bound themselves not to adore any deity but Allah to obey the Prophet to abstain from theft, adultery, infanticide, lying and backbiting. Thus was fulfilled the prophecy embodied in the Surah Al Fath in the Quran.
During his stay at Mecca, the Prophet dispatched his principal disciples in every direction to preach Islam among the wild tribes of the desert and call them to the true religion of Allah. He sent small detachments of his troops into the suburbs who destroyed the temples of Al Uzza, Suwaa, and Manat, the three famous idols in the temples of the neighboring tribes. The Prophet gave strict orders that these expeditions should be carried out in a peaceable manner. These injunctions were obeyed in all cases, with one exception. The troops under Khalid Ibn Al-Walid, the fierce newly-converted warrior, killed a few of the Bani Jazima. When the news of this wanton bloodshed reached the Prophet, he was deeply grieved and exclaimed: "Oh, my Lord, I am innocent of what Khalid has done." He dispatched a large sum of money for the widows and orphans of the slain and severely rebuked Khalid.
At this time the tribes of Hawazin and Thakif showed unwillingness to render obedience to the Muslims without resistance. They formed a league with the intention of attacking the Prophet, but he was vigilant enough to frustrate their plan. A big battle was fought with this new enemy of Islam near Hunain, a deep and narrow defile nine miles northeast of Mecca. The idolaters were utterly defeated. One body of the enemy, consisting chiefly of the Thakif tribe, took refuge in their fortified city of Ta'if, which eight or nine years before had dismissed the Prophet from within its walls with injuries and insults. The remainder of the defeated force, consisting principally of the Hawazin, sought at a camp in the valley of Autas. This camp was raided by the Muslim troops. The families of the Hawazin, their flocks and herds with all their other effects, were captured by the troops of the Prophet. Ta'if was then besieged for a few days only, after which the Prophet raised the siege, well knowing that the people of Ta'if would soon be forced by circumstances to submit without bloodshed. Returning to his camp where the prisoners of Hawazin were left safely, the Prophet found a deputation from this hostile tribe who begged him to set free their families. The Prophet replied that he was willing to give back his own share of those captives and that of the children of Abdul Muttalib, but that he could not force his followers to abandon the fruits of their victory. The disciples followed the generous example of their teacher. The hearts of several members of the Thakir tribe were so influenced by this that they offered their allegiance and soon became earnest Muslims. The Prophet now returned to Medina fully satisfied with the achievements of his mission.
The ninth year of the hijrah is known as the Year of Embassies, as being the year in which the various tribes of Arabia submitted to the claim of the Prophet and sent embassies to render homage to him.
These tribes had been awaiting the issue of the war between Muhammad and the Quraish; but as soon as the tribe - the principal of the whole nation and the descendants of Ishmael, whose prerogatives none offered to dispute - had submitted, they were satisfied that it was not in their power to oppose Muhammad. Hence their embassies flocked into Medina to make their submission to him. The conquest of Mecca decided the fate of idolatry in Arabia. Now deputations began to arrive from all sides to render the adherence to Islam of various tribes. Among the rest, five princes of the tribe of Himyar professed Islam and sent ambassadors to notify Muhammad of the same. These were the princes of Yemen, Mahra, Oman, and Yamama.
The idolaters of Ta'if, the very people who had driven the Messenger of Islam from their midst with violence and contempt, now sent a deputation to pray forgiveness and ask to be numbered among his followers. They begged, however, for temporary preservation of their idols. As a last appeal they begged for one month of grace only. But even this was not conceded. The Prophet said Islam and the idols could not exist together. They then begged for exemption from the daily prayers. The Prophet replied that without devotion, religion would be nothing. At last they submitted to all that was required of them. They, however, asked to be exempted from destroying the idols with their own hands. This was granted. The Prophet selected Abu Sufyan and Mughira to destroy the idols of Ta'if, the chief of which was the notorious idol of Al-Lat. This was carried out amidst cries of despair and grief from the women of Ta'if.
The conversion of this tribe of Ta'if is worthy of notice. This tribe, which hither to had proved hostile to the new faith, was noted among the Arabs for its idolatrous priesthood. A small detachment under Ali was sent to reduce them to obedience and to destroy their idols. The prince of the tribe was 'Adi, the son of the famous Hatim, whose generosity was spoken of all over Arabia. On the approach of the Muslim force, Adi fled to Syria, leaving his sister with his principal clansmen, to fall into the hands of the Muslims. These were conducted by Ali with every sign of respect and sympathy to Medina. When the daughter of Hatim came before the Prophet, she addressed him in the following words: "Messenger of Allah, my father is dead; my brother, my only relation fled into the mountains on the approach of the Muslims. I cannot ransom myself; I count on your generosity for my deliverance. My father was an illustrious man, the prince of his tribe, a man who ransomed prisoners, protected the honor of women, fed the poor, cothe afflicted, and was deaf to no appeal." The Prophet replied: "Your father had the virtues of a true Muslim; if it were permitted to invoke the mercy of Allah on any whose life was passed in idolatry, I would pray to Allah for mercy for the soul of Hatim." Then, addressing the Muslims around him, he said: "the daughter of Hatim is free, her father was a generous and humane man; Allah loves and rewards the merciful." With the daughter of Hatim, all her people were set at liberty. She proceeded to Syria and related to her brother the generosity of Muhammad. 'Adi, touched by gratitude, hastened to Medina, where he was kindly received by the Prophet. He professed Islam and returned to his people and persuaded them to abandon idolatry. They all submitted and became devoted Muslims.
Hitherto no prohibition had been enforced against idolaters entering the Holy Ka'ba, or performing their abominable rites within the sacred precincts. Towards the end of the ninth year of the hijrah, during the month of pilgrimage 'Ali was delegated by the Prophet to read a proclamation that ran as follows: "No idolater shall after this year perform the pilgrimage; no one shall make the circuit of the Ka'ba naked (such a disgraceful custom was practiced by the pagan Arabs); and treaty with the Prophet shall continue in force but four months are allowed to every man to return to his territories; after that there will be no obligation on the Prophet, except towards those with whom treaties have been concluded."
The vast multitude who had listened to the above declaration returned to their homes, and before the following year was over the majority of them were Muslims.
During the tenth year of the hijrah, as in the preceding one, numerous embassies continued to pour into Medina from all parts of Arabia, to testify to the allegiance of their chiefs and their tribes. Teachers were sent by the Prophet into the different provinces to teach the new converts the principles and precepts of Islam. These teachers were invariably given the following injunctions when they were about to depart on their mission: "Deal gently with the people, and be not harsh; cheer them, and do not look down upon them with contempt. You will meet with many believers in the Holy Scriptures, who will ask you: 'What is the key to heaven?' Answer them it (the key to heaven) is to bear witness to the divine truth and to do good."
