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

(391) See you not (O Muhammad صلى الله عليه وسلم) that Allah, He it is Whom glorify whosoever is in the heavens and the earth, and the birds with wings out-spread (in their flight)?. Of each one He (Allah) knows indeed his Salat (prayer) and his glorification, [or everyone knows his Salat (prayer) and his glorification]; and Allah is All-Aware of what they do.

(392) Allah has created every moving (living) creature from water. Of them there are some that creep on their bellies, and some that walk on two legs, and some that walk on four. Allah creates what He wills. Verily Allah is Able to do all things.

(393) They swear by Allah their strongest oaths, that if only you would order them, they would leave (their homes for fighting in Allah's Cause). Say: "Swear you not; (this) obedience (of yours) is known (to be false). Verily, Allah knows well what you do."

(394) Certainly, to Allah belongs all that is in the heavens and the earth. Surely, He knows your condition and (He knows) the Day when they will be brought back to Him, then He will inform them of what they did. And Allah is All-Knower of everything.

(395) Thus they (false gods - all deities other than Allah) will belie you (polytheists) regarding what you say (that they are gods besides Allah): then you can neither avert (the punishment), nor get help. And whoever among you does wrong (i.e. sets up rivals to Allah), We shall make him taste a great torment.

(396) And We shall turn to whatever deeds they (disbelievers, polytheists, sinners) did, and We shall make such deeds as scattered floating particles of dust.

(397) And it is He Who has created man from water, and has appointed for him kindred by blood, and kindred by marriage. And your Lord is Ever All-Powerful to do what He wills.

(398) And when it is said to them: "Prostrate yourselves to the Most Gracious (Allah)! they say: "And what is the Most Gracious? Shall we fall down in prostration to that which you (O Muhammad صلى الله عليه وسلم) command us?" And it increases in them only aversion.

(399) So they have indeed denied (the truth - this Qur'an), then the news of what they mocked at will come to them.

(400) Fir'aun (Pharaoh) said: "And what is the Lord of the 'Alamin (mankind, jinn and all that exists)?"
