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

(271) And eat not of that whereon Allah's name hath not been mentioned, for lo! it is abomination. Lo! the devils do inspire their minions to dispute with you. But if ye obey them, ye will be in truth idolaters.

(272) Is he who was dead and We have raised him unto life, and set for him a light wherein he walketh among men, as him whose similitude is in utter darkness whence he cannot emerge? Thus is their conduct made fairseeming for the disbelievers.

(273) And whomsoever it is Allah's will to guide, He expandeth his bosom unto the Surrender, and whomsoever it is His Will to send astray, He maketh his bosom close and narrow as if he were engaged in sheer ascent. Thus Allah layeth ignominy upon those who believe not.

(274) O ye assembly of the jinn and humankind! Came there not unto you messengers of your own who recounted unto you My tokens and warned you of the meeting of this your Day? They will say: We testify against ourselves. And the life of the world beguiled them. And they testify against themselves that they were disbelievers.

(275) Thy Lord is the Absolute, the Lord of Mercy. if He will, He can remove you and can cause what He will to follow after you, even as He raised you from the seed of other folk.

(276) And they say: That which is in the bellies of such cattle is reserved for our males and is forbidden to our wives; but if it be born dead, then they (all) may be partakers thereof. He will reward them for their attribution (of such ordinances unto Him). Lo, He is Wise, Aware.

(277) Eight pairs: Of the sheep twain, and of the goats twain. Say: Hath He forbidden the two males or the two females, or that which the wombs of the two females contain? Expound to me (the case) with knowledge, if ye are truthful.

(278) Say: I find not in that which is revealed unto me aught prohibited to an eater that he eat thereof, except it be carrion, or blood poured forth, or swineflesh - for that verily is foul - or the abomination which was immolated to the name of other than Allah. But whoso is compelled (thereto), neither craving nor transgressing, (for him) lo! thy Lord is Forgiving, Merciful.

(279) So if they give the lie to thee (Muhammad), say: Your Lord is a Lord of All-Embracing Mercy, and His wrath will never be withdrawn from guilty folk.

(280) Say: Come, bring your witnesses who can bear witness that Allah forbade (all) this. And if they bear witness, do not thou bear witness with them. Follow thou not the whims of those who deny Our revelations, those who believe not in the Hereafter and deem (others) equal with their Lord.
