The word(s) "if" appears 1307 time(s) in 1079 verse(s) in Quran in Muhammad Pickthal translation.

(291) They said: Our Lord! We have wronged ourselves. if thou forgive us not and have not mercy on us, surely we are of the lost!

(292) O Children of Adam! Let not Satan seduce you as he caused your (first) parents to go forth from the Garden and tore off from them their robe (of innocence) that he might manifest their shame to them. Lo! he seeth you, he and his tribe, from whence ye see him not. Lo! We have made the devils protecting friends for those who believe not.

(293) Say: Who hath forbidden the adornment of Allah which He hath brought forth for His bondmen, and the good things of His providing? Say: Such, on the Day of Resurrection, will be only for those who believed during the life of the world. Thus do we detail Our revelations for people who have knowledge.

(294) Who doeth greater wrong than he who inventeth a lie concerning Allah or denieth Our tokens. (For such) their appointed portion of the Book (of destiny) reacheth them till, when Our messengers come to gather them, they say: Where (now) is that to which ye cried beside Allah? They say: They have departed from us. And they testify against themselves that they were disbelievers.

(295) And We remove whatever rancour may be in their hearts. Rivers flow beneath them. And they say: The praise to Allah, Who hath guided us to this. We could not truly have been led aright if Allah had not guided us. Verily the messengers of our Lord did bring the Truth. And it is cried unto them: This is the Garden. Ye inherit it for what ye used to do.

(296) Who took their religion for a sport and pastime, and whom the life of the world beguiled. So this day We have forgotten them even as they forgot the meeting of this their Day and as they used to deny Our tokens.

(297) Await they aught save the fulfilment thereof? On the day when the fulfilment thereof cometh, those who were before forgetful thereof will say: The messengers of our Lord did bring the Truth! Have we any intercessors, that they may intercede for us? Or can we be returned (to life on earth), that we may act otherwise than we used to act? They have lost their souls, and that which they devised hath failed them.

(298) They said: Hast come unto us that we should serve Allah alone, and forsake what our fathers worshipped? Then bring upon us that wherewith thou threatenest us if thou art of the truthful!

(299) So they hamstrung the she-camel, and they flouted the commandment of their Lord, and they said: O Salih! Bring upon us that thou threatenest if thou art indeed of those sent (from Allah).

(300) And We rescued him and his household, save his wife, who was of those who stayed behind.
