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

(551) Alif-Lam-Mim-Ra. [These letters are one of the miracles of the Qur'an; and none but Allah (Alone) knows their meanings]. These are the Verses of the Book (the Qur'an), and that which has been revealed unto you (Muhammad صلى الله عليه و سلم) from your Lord is the truth, but most men believe not.

(552) And if you (O Muhammad صلى الله عليه و سلم) wonder (at these polytheists who deny your message of Islamic Monotheism and have taken besides Allah others for worship who can neither harm nor benefit), then wondrous is their saying: "When we are dust, shall we indeed then be (raised) in a new creation?" They are those who disbelieved in their Lord! They are those who will have iron chains tying their hands to their necks. They will be the dwellers of the Fire to abide therein.

(553) And Ar-Ra'd (thunder) glorifies and praises Him, and so do the angels because of His Awe. He sends the thunderbolts, and therewith He strikes whom He wills, yet they (disbelievers) dispute about Allah. And He is Mighty in strength and Severe in punishment.

(554) For those who answered their Lord's Call [believed in the Oneness of Allah and followed His Messenger Muhammad صلى الله عليه و سلم i.e. Islamic Monotheism] is Al-Husna (i.e. Paradise). But those who answered not His Call (disbelieved in the Oneness of Allah and followed not His Messenger Muhammad صلى الله عليه و سلم), if they had all that is in the earth together with its like, they would offer it in order to save themselves (from the torment, but it will be in vain). For them there will be the terrible reckoning. Their dwelling-place will be Hell; and worst indeed is that place for rest.

(555) And those who break the Covenant of Allah, after its ratification, and sever that which Allah has commanded to be joined (i.e. they sever the bond of kinship and are not good to their relatives), and work mischief in the land, on them is the curse (i.e. they will be far away from Allah's Mercy), and for them is the unhappy (evil) home (i.e. Hell) .

(556) Allah increases the provision for whom He wills, and straitens (it for whom He wills), and they rejoice in the life of the world, whereas the life of this world as compared with the Hereafter is but a brief passing enjoyment.

(557) Those who believed (in the Oneness of Allah - Islamic Monotheism), and work righteousness, Tuba (all kinds of happiness or name of a tree in Paradise) is for them and a beautiful place of (final) return.

(558) And if there had been a Qur'an with which mountains could be moved (from their places), or the earth could be cloven asunder, or the dead could be made to speak (it would not have been other than this Qur'an). But the decision of all things is certainly with Allah. Have not then those who believed yet known that had Allah willed, He could have guided all mankind? And a disaster will not cease to strike those who disbelieved because of their (evil) deeds or it (i.e. the disaster) settles close to their homes, until the Promise of Allah comes to pass. Certainly, Allah breaks not His Promise.

(559) For them is a torment in the life of this world, and certainly, harder is the torment of the Hereafter. And they have no Waq (defender or protector) against Allah.

(560) See they not that We gradually reduce the land (of the disbelievers, by giving it to the believers, in war victories) from its outlying borders. And Allah judges, there is none to put back His Judgement and He is Swift at reckoning.
