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

(431) They shall have good news in this world's life and in the hereafter; there is no changing the words of Allah; that is the mighty achievement.

(432) And recite to them the story of Nuh when he said to his people: O my people! if my stay and my reminding (you) by the communications of Allah is hard on you-- yet on Allah do I rely-- then resolve upon your affair and (gather) your associates, then let not your affair remain dubious to you, then have it executed against me and give me no respite:

(433) But if you turn back, I did not ask for any reward from you; my reward is only with Allah, and I am commanded that I should be of those who submit.

(434) And Musa said: O my people! if you believe in Allah, then rely on Him (alone) if you submit (to Allah).

(435) And Musa said: Our Lord! surely Thou hast given to Firon and his chiefs finery and riches in this world's life, to this end, our Lord, that they lead (people) astray from Thy way: Our Lord! destroy their riches and harden their hearts so that they believe not until they see the painful punishment.

(436) But if you are in doubt as to what We have revealed to you, ask those who read the Book before you; certainly the truth has come to you from your Lord, therefore you should not be of the disputers.

(437) And wherefore was there not a town which should believe so that their belief should have profited them but the people of Yunus? When they believed, We removed from them the chastisement of disgrace in this world's life and We gave them provision till a time.

(438) And if your Lord had pleased, surely all those who are in the earth would have believed, all of them; will you then force men till they become believers?

(439) Say: O people! if you are in doubt as to my religion, then (know that) I do not serve those whom you serve besides Allah but I do serve Allah, Who will cause you to die, and I am commanded that I should be of the believers.

(440) And do not call besides Allah on that which can neither benefit you nor harm you, for if you do then surely you will in that case be of the unjust.
