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

(11) Then, after that, your hearts were hardened and became as stones or even worse in hardness. And indeed, there are stones out of which rivers gush forth, and indeed, there are of them (stones) which split asunder so that water flows from them, and indeed, there are of them (stones) which fall down for fear of Allah. And Allah is not unaware of what you do.

(12) And when they (Jews) meet those who believe (Muslims), they say, "We believe", but when they meet one another in private, they say, "Shall you (Jews) tell them (Muslims) what Allah has revealed to you [Jews, about the description and the qualities of Prophet Muhammad صلى الله عليه وسلم, that which are written in the Taurat (Torah)] , that they (Muslims) may argue with you (Jews) about it before your Lord?" Have you (Jews) then no understanding?

(13) Know they (Jews) not that Allah knows what they conceal and what they reveal?

(14) Then woe to those who write the Book with their own hands and then say, "This is from Allah," to purchase with it a little price! Woe to them for what their hands have written and woe to them for that they earn thereby.

(15) And they (Jews) say, "The Fire (i.e. Hell-fire on the Day of Resurrection) shall not touch us but for a few numbered days." Say (O Muhammad صلى الله عليه وسلم to them): "Have you taken a covenant from Allah, so that Allah will not break His Covenant? Or is it that you say of Allah what you know not?"

(16) After this, it is you who kill one another and drive out a party of you from their homes, assist (their enemies) against them, in sin and transgression. And if they come to you as captives, you ransom them, although their expulsion was forbidden to you. Then do you believe in a part of the Scripture and reject the rest? Then what is the recompense of those who do so among you, except disgrace in the life of this world, and on the Day of Resurrection they shall be consigned to the most grievous torment. And Allah is not unaware of what you do.

(17) And indeed, We gave Musa (Moses) the Book and followed him up with a succession of Messengers. And We gave 'Îsa (Jesus), the son of Maryam (Mary), clear signs and supported him with Ruh-ul-Qudus [Jibrael (Gabriel عليه السلام)]. Is it that whenever there came to you a Messenger with what you yourselves desired not, you grew arrogant? Some you disbelieved and some you killed.

(18) And when there came to them (the Jews), a Book (this Qur'an) from Allah confirming what is with them [the Taurat (Torah) and the Injeel (Gospel)], although aforetime they had invoked Allah (for coming of Muhammad صلى الله عليه وسلم) in order to gain victory over those who disbelieved, then when there came to them that which they had recognised, they disbelieved in it. So let the Curse of Allah be on the disbelievers.

(19) 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?"

(20) 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."
