The word(s) "what" appears 845 time(s) in 697 verse(s) in Quran in Mohsin Khan translation.

(141) And We have sent down to you (O Muhammad صلى الله عليه وسلم) the Book (this Qur'an) in truth, confirming the Scripture that came before it and Muhaymin (trustworthy in highness and a witness) over it (old Scriptures) . So judge among them by what Allah has revealed, and follow not their vain desires, diverging away from the truth that has come to you. To each among you, We have prescribed a law and a clear way. If Allah had willed, He would have made you one nation, but that (He) may test you in what He has given you; so compete in good deeds. The return of you (all) is to Allah; then He will inform you about that in which you used to differ.

(142) And so judge (you O Muhammad صلى الله عليه وسلم) among them by what Allah has revealed and follow not their vain desires, but beware of them lest they turn you (O Muhammad صلى الله عليه وسلم) far away from some of that which Allah has sent down to you. And if they turn away, then know that Allah's Will is to punish them for some sins of theirs. And truly, most of men are Fasiqun (rebellious and disobedient to Allah).

(143) And you see those in whose hearts there is a disease (of hypocrisy), they hurry to their friendship, saying: "We fear lest some misfortune of a disaster may befall us." Perhaps Allah may bring a victory or a decision according to His Will. Then they will become regretful for what they have been keeping as a secret in themselves.

(144) When they come to you, they say: "We believe." But in fact they enter with (an intention of) disbelief and they go out with the same. And Allah knows all what they were hiding.

(145) The Jews say: "Allah's Hand is tied up (i.e. He does not give and spend of His Bounty)." Be their hands tied up and be they accursed for what they uttered. Nay, both His Hands are widely outstretched. He spends (of His Bounty) as He wills. Verily, the Revelation that has come to you from your Lord (Allah) increases in most of them (their) obstinate rebellion and disbelief. We have put enmity and hatred amongst them till the Day of Resurrection. Every time they kindled the fire of war, Allah extinguished it; and they (ever) strive to make mischief on the earth. And Allah does not like the Mufsidun (mischief-makers).

(146) And if only they had acted according to the Taurat (Torah), the Injeel (Gospel), and what has (now) been sent down to them from their Lord (the Qur'an), they would surely have gotten provision from above them and from underneath their feet. There are from among them people who are on the right course (i.e. they act on the revelation and believe in Prophet Muhammad صلى الله عليه وسلم as 'Abdullah bin Salam رضي الله عنه), but many of them do evil deeds.

(147) Say (O Muhammad صلى الله عليه وسلم) "O people of the Scripture (Jews and Christians)! You have nothing (as regards guidance) till you act according to the Taurat (Torah), the Injeel (Gospel), and what has (now) been sent down to you from your Lord (the Qur'an)." Verily, that which has been sent down to you (Muhammad صلى الله عليه وسلم) from your Lord increases in most of them (their) obstinate rebellion and disbelief. So be not sorrowful over the people who disbelieve.

(148) Verily, We took the covenant of the Children of Israel and sent Messengers to them. Whenever there came to them a Messenger with what they themselves desired not, - a group of them they called liars, and others among them they killed.

(149) They thought there will be no Fitnah (trial or punishment), so they became blind and deaf; after that Allah turned to them (with Forgiveness); yet again many of them became blind and deaf. And Allah is the All-Seer of what they do.

(150) Surely, disbelievers are those who said: "Allah is the third of the three (in a Trinity)." But there is no Ilah (god) (none who has the right to be worshipped) but One Ilah (God -Allah). And if they cease not from what they say, verily, a painful torment will befall on the disbelievers among them.
