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

(21) Those are they who have bought the life of this world at the price of the Hereafter. Their torment shall not be lightened nor shall they be helped.

(22) And when it is said to them (the Jews), "Believe in what Allah has sent down," they say, "We believe in what was sent down to us." And they disbelieve in that which came after it, while it is the truth confirming what is with them. Say (O Muhammad صلى الله عليه وسلم to them): "Why then have you killed the Prophets of Allah aforetime, if you indeed have been believers?"

(23) And (remember) when We took your covenant and We raised above you the Mount (saying), "Hold firmly to what We have given you and hear (Our Word)." They said, "We have heard and disobeyed." And their hearts absorbed (the worship of) the calf because of their disbelief. Say: "Worst indeed is that which your faith enjoins on you if you are believers."

(24) Say to (them): "if the home of the Hereafter with Allah is indeed for you specially and not for others, of mankind, then long for death if you are truthful."

(25) And verily, you will find them (the Jews) the greediest of mankind for life and (even greedier) than those who ascribe partners to Allah (and do not believe in Resurrection - Majus, pagans, and idolaters). Everyone of them wishes that he could be given a life of a thousand years. But the grant of such life will not save him even a little from (due) punishment. And Allah is All-Seer of what they do.

(26) And indeed We have sent down to you manifest Ayat (these Verses of the Qur'an which inform in detail about the news of the Jews and their secret intentions, etc.), and none disbelieve in them but Fasiqun (those who rebel against Allah's Command).

(27) And when there came to them a Messenger from Allah (i.e. Muhammad صلى الله عليه وسلم) confirming what was with them, a party of those who were given the Scripture threw away the Book of Allah behind their backs as if they did not know!

(28) They followed what the Shayatin (devils) gave out (falsely of the magic) in the lifetime of Sulaiman (Solomon). Sulaiman did not disbelieve, but the Shayatin (devils) disbelieved, teaching men magic and such things that came down at Babylon to the two angels, Harut and Marut, but neither of these two (angels) taught anyone (such things) till they had said, "We are only for trial, so disbelieve not (by learning this magic from us)." And from these (angels) people learn that by which they cause separation between man and his wife, but they could not thus harm anyone except by Allah's Leave. And they learn that which harms them and profits them not. And indeed they knew that the buyers of it (magic) would have no share in the Hereafter. And how bad indeed was that for which they sold their ownselves, if they but knew.

(29) And if they had believed, and guarded themselves from evil and kept their duty to Allah, far better would have been the reward from their Lord, if they but knew!

(30) Many of the people of the Scripture (Jews and Christians) wish that if they could turn you away as disbelievers after you have believed, out of envy from their ownselves, even after the truth (that Muhammad صلى الله عليه وسلم is Allah's Messenger) has become manifest unto them. But forgive and overlook, till Allah brings His Command. Verily, Allah is Able to do all things.
