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

(651) Then what is wrong with them (i.e. the polytheists, the disbelievers) that they turn away from (receiving) admonition?

(652) On that Day man will be informed of what he sent forward (of his evil good deeds), and what he left behind (of his good or evil traditions).

(653) Surely, what you are promised must come to pass.

(654) For what Day are these signs postponed?

(655) And what will explain to you what is the Day of Sorting Out?

(656) Then in what statement after this (the Qur'an) will they believe?

(657) what are they asking (one another) about?

(658) (From) the Lord of the heavens and the earth, and whatsoever is in between them, the Most Gracious, with Whom they cannot dare to speak (on the Day of Resurrection except by His Leave).

(659) The Day that Ar-Ruh [Jibril (Gabriel) or another angel] and the angels will stand forth in rows, they will not speak except him whom the Most Gracious (Allah) allows, and he will speak what is right.

(660) The Day when man shall remember what he strove for.
