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

(431) And (bidding you): Ask pardon of your Lord and turn to Him repentant. He will cause you to enjoy a fair estate until a time appointed. He giveth His bounty unto every bountiful one. But if ye turn away, lo! (then) I fear for you the retribution of an awful Day.

(432) And He it is Who created the heavens and the earth in six Days - and His Throne was upon the water - that He might try you, which of you is best in conduct. Yet if thou (O Muhammad) sayest: Lo! ye will be raised again after death! those who disbelieve will surely say: This is naught but mere magic.

(433) And if We delay for them the doom until a reckoned time, they will surely say: What withholdeth it? Verily on the day when it cometh unto them, it cannot be averted from them, and that which they derided will surround them.

(434) And if we cause man to taste some mercy from Us and afterward withdraw it from him, lo! he is despairing, thankless.

(435) And if We cause him to taste grace after some misfortune that had befallen him, he saith: The ills have gone from me. Lo! he is exultant, boastful;

(436) Or they say: He hath invented it. Say: Then bring ten surahs, the like thereof, invented, and call on everyone ye can beside Allah, if ye are truthful!

(437) And if they answer not your prayer, then know that it is revealed only in the knowledge of Allah; and that there is no Allah save Him. Will ye then be (of) those who surrender?

(438) Whoso desireth the life of the world and its pomp, We shall repay them their deeds herein, and therein they will not be wronged.

(439) He said: O my people! Bethink you, if I rely on a clear proof from my Lord and there hath come unto me a mercy from His presence, and it hath been made obscure to you, can we compel you to accept it when ye are averse thereto?

(440) And, O my people! who would deliver me from Allah if I thrust them away? Will ye not then reflect?
