The word(s) "if" appears 1640 time(s) in 1298 verse(s) in Quran in Mohsin Khan translation.

(461) Verily, the likeness of (this) worldly life is as the water (rain) which We send down from the sky; so by it arises the intermingled produce of the earth of which men and cattle eat: until when the earth is clad in its adornments and is beautified, and its people think that they have all the powers of disposal over it, Our Command reaches it by night or by day and We make it like a clean-mown harvest, as if it had not flourished yesterday! Thus do We explain the Ayat (proofs, evidence, verses, lessons, signs, revelations, laws, etc.) in detail for the people who reflect.

(462) And the Day whereon We shall gather them all together, then We shall say to those who did set partners in worship with Us: "Stop at your place! You and your partners (whom you had worshipped in the worldly life)." then We shall separate them, and their (Allah's so-called) partners shall say: "It was not us that you used to worship."

(463) Thus is the Word of your Lord justified against those who rebel (disobey Allah) that they will not believe (in the Oneness of Allah and in Muhammad صلى الله عليه وسلم as the Messenger of Allah).

(464) Or do they say: "He (Muhammad صلى الله عليه وسلم) has forged it?" Say: "Bring then a Surah (chapter) like unto it, and call upon whomsoever you can besides Allah, if you are truthful!"

(465) And if they belie you, say: "For me are my deeds and for you are your deeds! You are innocent of what I do, and I am innocent of what you do!"

(466) And on the Day when He shall gather (resurrect) them together, (it will be) as if they had not stayed (in the life of this world and graves) but an hour of a day. They will recognise each other. Ruined indeed will be those who denied the Meeting with Allah, and were not guided.

(467) Whether We show you (in your lifetime, O Muhammad صلى الله عليه وسلم) some of what We promise them (the torment), or We cause you to die - still unto Us is their return, and moreover, Allah is Witness over what they used to do.

(468) And they say: "When will be this promise (the torment or the Day of Resurrection), if you speak the truth?"

(469) Say: "Tell me, if His torment should come to you by night or by day, which portion thereof would the Mujrimun (disbelievers, polytheists, sinners, criminals) hasten on ?"

(470) And if every person who had wronged (by disbelieving in Allah and by worshipping others besides Allah) possessed all that is on the earth and sought to ransom himself therewith (it will not be accepted), and they would feel in their hearts regret when they see the torment, and they will be judged with justice, and no wrong will be done unto them.
