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

(501) Alif Lam Mim Ra. These are the verses of the Book; and that which is revealed to you from your Lord is the truth, but most people do not believe.

(502) And if you would wonder, then wondrous is their saying: What! when we are dust, shall we then certainly be in a new creation? These are they who disbelieve in their Lord, and these have chains on their necks, and they are the inmates of the fire; in it they shall abide.

(503) Allah amplifies and straitens the means of subsistence for whom He pleases; and they rejoice in this world's life, and this world's life is nothing compared with the hereafter but a temporary enjoyment.

(504) And even if there were a Quran with which the mountains were made to pass away, or the earth were travelled over with it, or the dead were made to speak thereby; nay! the commandment is wholly Allah's, Have not yet those who believe known that if Allah please He would certainly guide all the people? And (as for) those who disbelieve, there will not cease to afflict them because of what they do a repelling calamity, or it will alight close by their abodes, until the promise of Allah comes about; surely Allah will not fail in (His) promise.

(505) They shall have chastisement in this world's life, and the chastisement of the hereafter is certainly more grievous, and they shall have no protector against Allah.

(506) And thus have We revealed it, a true judgment in Arabic, and if you follow their low desires after what has come to you of knowledge, you shall not have against Allah any guardian or a protector.

(507) Do they not see that We are bringing destruction upon the land by curtailing it of its sides? And Allah pronounces a doom-- there is no repeller of His decree, and He is swift to take account.

(508) Alif Lam Ra. (This is) a Book which We have revealed to you that you may bring forth men, by their Lord's permission from utter darkness into light-- to the way of the Mighty, the Praised One,

(509) (To) those who love this world's life more than the hereafter, and turn away from Allah's path and desire to make it crooked; these are in a great error.

(510) And when your Lord made it known: if you are grateful, I would certainly give to you more, and if you are ungrateful, My chastisement is truly severe.
