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

(171) And with Him are the keys of the Ghaib (all that is hidden), none knows them but He. And He knows whatever there is in the land and in the sea; not a leaf falls, but he knows it. There is not a grain in the darkness of the earth nor anything fresh or dry, but is written in a Clear Record.

(172) And who can be more unjust than he who invents a lie against Allah, or says: "A revelation has come to me" whereas no revelation has come to him in anything ; and who says, "I will reveal the like of what Allah has revealed." And if you could but see when the Zalimun (polytheists and wrong-doers) are in the agonies of death, while the angels are stretching forth their hands (saying): "Deliver your souls! This day you shall be recompensed with the torment of degradation because of what you used to utter against Allah other than the truth. And you used to reject His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) with disrespect! "

(173) Follow what has been revealed to you (O Muhammad صلى الله عليه وسلم) from your Lord, La ilaha illa Huwa (none has the right to be worshipped but He) and turn aside from Al-Mushrikun

(174) And they swear their strongest oaths by Allah, that if there came to them a sign, they would surely believe therein. Say: "Signs are but with Allah and what will make you (Muslims) perceive that (even) if it (the sign) came, they will not believe?"

(175) (And this is in order) that the hearts of those who disbelieve in the Hereafter may incline to such (deceit), and that they may remain pleased with it, and that they may commit what they are committing (all kinds of sins and evil deeds).

(176) And why should you not eat of that (meat) on which Allah's Name has been pronounced (at the time of slaughtering the animal), while He has explained to you in detail what is forbidden to you, except under compulsion of necessity? And surely many do lead (mankind) astray by their own desires through lack of knowledge. Certainly your Lord knows best the transgressors.

(177) For them will be the home of peace (Paradise) with their Lord. And He will be their Wali (Helper and Protector) because of what they used to do.

(178) For all there will be degrees (or ranks) according to what they did. And your Lord is not unaware of what they do.

(179) And according to their claim, they say that such and such cattle and crops are forbidden, and none should eat of them except those whom we allow. And (they say) there are cattle forbidden to be used for burden (or any other work), and cattle on which (at slaughtering) the Name of Allah is not pronounced; lying against Him (Allah). He will recompense them for what they used to fabricate.

(180) And they say: "what is in the bellies of such and such cattle (milk or foetus) is for our males alone, and forbidden to our females (girls and women), but if it is born dead, then all have shares therein." He will punish them for their attribution (of such false orders to Allah). Verily, He is All-Wise, All-Knower. (Tafsir At-Tabari).
