The word(s) "if" appears 1358 time(s) in 1110 verse(s) in Quran in Muhammad Habib Shakir translation.

(421) The likeness of this world's life is only as water which We send down from the cloud, then the herbage of the earth of which men and cattle eat grows luxuriantly thereby, until when the earth puts on its golden raiment and it becomes garnished, and its people think that they have power over it, Our command comes to it, by night or by day, so We render it as reaped seed; produce, as though it had not been in existence yesterday; thus do We make clear the communications for a people who reflect.

(422) And (as for) those who have earned evil, the punishment of an evil is the like of it, and abasement shall come upon them-- they shall have none to protect them from Allah-- as if their faces had been covered with slices of the dense darkness of night; these are the inmates of the fire; in it they shall abide.

(423) And this Quran is not such as could be forged by those besides Allah, but it is a verification of that which is before it and a clear explanation of the book, there is no doubt in it, from the Lord of the worlds.

(424) Or do they say: He has forged it? Say: Then bring a chapter like this and invite whom you can besides Allah, if you are truthful.

(425) And if they call you a liar, say: My work is for me and your work for you; you are clear of what I do and I am clear of what you do.

(426) And if We show you something of what We threaten them with, or cause you to die, yet to Us is their return, and Allah is the bearer of witness to what they do.

(427) And they say: When will this threat come about, if you are truthful?

(428) Say: Tell me if His punishment overtakes you by night or by day! what then is there of it that the guilty would hasten on?

(429) And if every soul that has done injustice had all that is in the earth, it would offer it for ransom, and they will manifest regret when they see the chastisement and the matter shall be decided between them with justice and they shall not be dealt with unjustly.

(430) He gives life and causes death, and to Him you shall be brought back.
