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

(371) And they ask you to hasten on the torment! And Allah fails not His Promise. And verily, a day with your Lord is as a thousand years of what you reckon.

(372) That He (Allah) may make what is thrown in by Shaitan (Satan) a trial for those in whose hearts is a disease (of hypocrisy and disbelief) and whose hearts are hardened. And certainly, the Zalimun (polytheists and wrong-doers) are in an opposition far-off (from the truth against Allah's Messenger and the believers).

(373) That is because Allah - He is the Truth (the only True God of all that exists, Who has no partners or rivals with Him), and what they (the polytheists) invoke besides Him, it is Batil (falsehood). And verily, Allah - He is the Most High, the Most Great.

(374) And if they argue with you (as regards the slaughtering of the sacrifices), say "Allah knows best of what you do.

(375) He knows what is before them, and what is behind them. And to Allah return all matters (for decision).

(376) And strive hard in Allah's Cause as you ought to strive (with sincerity and with all your efforts that His Name should be superior). He has chosen you (to convey His Message of Islamic Monotheism to mankind by inviting them to His religion of Islam), and has not laid upon you in religion any hardship: it is the religion of your father Ibrahim (Abraham) (Islamic Monotheism). It is He (Allah) Who has named you Muslims both before and in this (the Qur'an), that the Messenger (Muhammad صلى الله عليه وسلم) may be a witness over you and you be witnesses over mankind! So perform As-Salat (Iqamat-as-Salat), give Zakat and hold fast to Allah [i.e. have confidence in Allah, and depend upon Him in all your affairs]. He is your Maula (Patron, Lord), what an Excellent Maula (Patron, Lord) and what an Excellent Helper!

(377) Verily, in this [what We did as regards drowning of the people of Nuh (Noah)], there are indeed Ayat (proofs, evidence, lessons, signs, etc. for men to understand), for sure We are ever putting (men) to the test.

(378) And the chiefs of his people who disbelieved and denied the Meeting in the Hereafter, and whom We had given the luxuries and comforts of this life, said: "He is no more than a human being like you, he eats of that which you eat, and drinks of what you drink.

(379) O (you) Messengers! Eat of the Tayyibat [all kinds of Halal foods which Allah has made lawful (meat of slaughtered eatable animals, milk products, fats, vegetables, fruits, etc.] and do righteous deeds. Verily! I am Well-Acquainted with what you do.

(380) But they (men) have broken their religion among them into sects, each group rejoicing in what is with it (as its beliefs).
