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

(331) Then there came after them an evil posterity who inherited the Book, taking only the frail good of this low life and saying: It will be forgiven us. And if the like good came to them, they would take it (too). Was not a promise taken from them in the Book that they would not speak anything about Allah but the truth, and they have read what is in it; and the abode of the hereafter is better for those who guard (against evil). Do you not then understand?

(332) And when We shook the mountain over them as if it were a covering overhead, and they thought that it was going to fall down upon them: Take hold of what We have given you with firmness, and be mindful of what is in it, so that you may guard (against evil).

(333) And if We had pleased, We would certainly have exalted him thereby; but he clung to the earth and followed his low desire, so his parable is as the parable of the dog; if you attack him he lolls out his tongue; and if you leave him alone he lolls out his tongue; this is the parable of the people who reject Our communications; therefore relate the narrative that they may reflect.

(334) They ask you about the hour, when will be its taking place? Say: The knowledge of it is only with my Lord; none but He shall manifest it at its time; it will be momentous in the heavens and the earth; it will not come on you but of a sudden. They ask you as if you were solicitous about it. Say: Its knowledge is only with Allah, but most people do not know.

(335) He it is Who created you from a single being, and of the same (kind) did He make his mate, that he might incline to her; so when he covers her she bears a light burden, then moves about with it; but when it grows heavy, they both call upon Allah, their Lord: if Thou givest us a good one, we shall certainly be of the grateful ones.

(336) And if you invite them to guidance, they will not follow you; it is the same to you whether you invite them or you are silent.

(337) Surely those whom you call on besides Allah are in a state of subjugation like yourselves; therefore call on them, then let them answer you if you are truthful.

(338) And if you invite them to guidance, they do not hear; and you see them looking towards you, yet they do not see.

(339) And if a false imputation from the Shaitan afflict you, seek refuge in Allah; surely He is Hearing, Knowing.

(340) They ask you about the windfalls. Say: The windfalls are for Allah and the Apostle. So be careful of (your duty to) Allah and set aright matters of your difference, and obey Allah and His Apostle if you are believers.
