In the case of those who say, "Our Lord is Allah", and, further, stand straight and steadfast, the angels descend on them (from time to time): "Fear ye not!" (they suggest), "Nor grieve! but receive the Glad Tidings of the Garden (of Bliss), the which ye were promised!
"We are your protectors in this life and in the Hereafter: therein shall ye have all that your souls shall desire; therein shall ye have all that ye ask for!-
"A hospitable gift from one Oft-Forgiving, Most Merciful!"
Who is better in speech than one who calls (men) to Allah, works righteousness, and says, "I am of those who bow in Islam"?
Nor can goodness and Evil be equal. Repel (Evil) with what is better: Then will he between whom and thee was hatred become as it were thy friend and intimate!
And no one will be granted such goodness except those who exercise patience and self-restraint,- none but persons of the greatest good fortune.
And if (at any time) an incitement to discord is made to thee by the Evil One, seek refuge in Allah. He is the One Who hears and knows all things.
