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

(621) whatsoever is in the heavens and whatsoever is on the earth glorifies Allah, the King (of everything), the Holy, the All-Mighty, the All-Wise.

(622) But they will never long for it (death), because of what (deeds) their hands have sent before them! And Allah knows well the Zalimun (polytheists, wrong-doers, disbelievers).

(623) Say (to them): "Verily, the death from which you flee will surely meet you, then you will be sent back to (Allah), the All-Knower of the unseen and the seen, and He will tell you what you used to do."

(624) They have made their oaths a screen (for their hypocrisy). Thus they hinder (men) from the Path of Allah. Verily, evil is what they used to do.

(625) And Allah grants respite to none when his appointed time (death) comes. And Allah is All-Aware of what you do.

(626) whatsoever is in the heavens and whatsoever is on the earth glorifies Allah. His is the dominion, and to Him belong all the praises and thanks, and He is Able to do all things.

(627) He it is Who created you, then some of you are disbelievers and some of you are believers. And Allah is All-Seer of what you do.

(628) He knows what is in the heavens and on earth, and He knows what you conceal and what you reveal. And Allah is the All-Knower of what is in the breasts (of men).

(629) The disbelievers pretend that they will never be resurrected (for the Account). Say (O Muhammad صلى الله عليه وسلم): Yes! By my Lord, you will certainly be resurrected, then you will be informed of (and recompensed for) what you did; and that is easy for Allah.

(630) Therefore, believe in Allah and His Messenger (Muhammad صلى الله عليه وسلم) and in the Light (this Qur'an) which We have sent down. And Allah is All-Aware of what you do.
