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

(151) They used not to forbid one another from Al-Munkar (wrong, evil-doing, sins, polytheism, disbelief) which they committed. Vile indeed was what they used to do.

(152) And had they believed in Allah, and in the Prophet (Muhammad صلى الله عليه وسلم) and in what has been revealed to him, never would they have taken them (the disbelievers) as Auliya' (protectors and helpers); but many of them are the Fasiqun (rebellious, disobedient to Allah).

(153) And when they (who call themselves Christians) listen to what has been sent down to the Messenger (Muhammad صلى الله عليه وسلم), you see their eyes overflowing with tears because of the truth they have recognised. They say: "Our Lord! We believe; so write us down among the witnesses.

(154) So because of what they said, Allah rewarded them Gardens under which rivers flow (in Paradise), they will abide therein forever. Such is the reward of Al-Muhsinun (the good-doers).

(155) Allah will not punish you for what is unintentional in your oaths, but He will punish you for your deliberate oaths; for its expiation feed ten Masakin (poor persons), on a scale of the average of that with which you feed your own families, or clothe them or manumit a slave. But whosoever cannot afford (that), then he should fast for three days. That is the expiation for the oaths when you have sworn . And protect your oaths (i.e. do not swear much) . Thus Allah make clear to you His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) that you may be grateful.

(156) Those who believe and do righteous good deeds, there is no sin on them for what they ate (in the past), if they fear Allah (by keeping away from His forbidden things), and believe and do righteous good deeds, and again fear Allah and believe, and once again fear Allah and do good deeds with Ihsan (perfection). And Allah loves the good-doers.

(157) O you who believe! Kill not the game while you are in a state of Ihram [for Hajj or 'Umrah (pilgrimage)], and whosoever of you kills it intentionally, the penalty is an offering, brought to the Ka'bah, of an eatable animal (i.e. sheep, goat, cow) equivalent to the one he killed, as adjudged by two just men among you; or, for expiation, he should feed Masakin (poor persons), or its equivalent in Saum (fasting), that he may taste the heaviness (punishment) of his deed. Allah has forgiven what is past, but whosoever commits it again, Allah will take retribution from him. And Allah is All-Mighty, All-Able of Retribution.

(158) And when it is said to them: "Come to what Allah has revealed and unto the Messenger (Muhammad صلى الله عليه وسلم for the verdict of that which you have made unlawful)." They say: "Enough for us is that which we found our fathers following," even though their fathers had no knowledge whatsoever nor guidance.

(159) O you who believe! Take care of your ownselves . If you follow the (right) guidance [and enjoin what is right (Islamic Monotheism and all that Islam orders one to do) and forbid what is wrong (polytheism, disbelief and all that Islam has forbidden)] no hurt can come to you from those who are in error. The return of you all is to Allah, then He will inform you about (all) that which you used to do.

(160) On the Day when Allah will gather the Messengers together and say to them: "what was the response you received (from men to your teaching)?" They will say: "We have no knowledge, verily, only You are the All-Knower of all that is hidden (or unseen)."
