The word(s) "what" appears 597 time(s) in 511 verse(s) in Quran in Muhammad Pickthal translation.

(191) He said: Know ye what ye did unto Joseph and his brother in your ignorance?

(192) Is he who knoweth that what is revealed unto thee from thy Lord is the truth like him who is blind? But only men of understanding heed;

(193) Had it been possible for a Lecture to cause the mountains to move, or the earth to be torn asunder, or the dead to speak, (this Qur'an would have done so). Nay, but Allah's is the whole command. Do not those who believe know that, had Allah willed, He could have guided all mankind? As for those who disbelieve, disaster ceaseth not to strike them because of what they do, or it dwelleth near their home until the threat of Allah come to pass. Lo! Allah faileth not to keep the tryst.

(194) Allah effaceth what He will, and establisheth (what He will), and with Him is the source of ordinance.

(195) Allah, unto Whom belongeth whatsoever is in the heavens and whatsoever is in the earth. and woe unto the disbelievers from an awful doom;

(196) Their messengers said: Can there be doubt concerning Allah, the Creator of the heavens and the earth? He calleth you that He may forgive you your sins and reprieve you unto an appointed term. They said: Ye are but mortals like us, who would fain turn us away from what our fathers used to worship. Then bring some clear warrant.

(197) Allah confirmeth those who believe by a firm saying in the life of the world and in the Hereafter, and Allah sendeth wrong-doers astray. And Allah doeth what He will.

(198) Deem not that Allah is unaware of what the wicked do. He but giveth them a respite till a day when eyes will stare (in terror),

(199) That Allah may repay each soul what it hath earned. Lo! Allah is swift at reckoning.

(200) He said: O Iblis! what aileth thee that thou art not among the prostrate?
