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

(361) Bear with what they say, and remember Our bondman David, lord of might, Lo! he was ever turning in repentance (toward Allah).

(362) And they say: what aileth us that we behold not men whom we were wont to count among the wicked?

(363) He said: O Iblis! what hindereth thee from falling prostrate before that which I have created with both My hands? Art thou too proud or art thou of the high exalted?

(364) If Allah had willed to choose a son, He could have chosen what He would of that which He hath created. Be He Glorified! He is Allah, the One, the Absolute.

(365) If ye are thankless, yet Allah is Independent of you, though He is not pleased with thanklessness for His bondmen; and if ye are thankful He is pleased therewith for you. No laden soul will bear another's load. Then unto your Lord is your return; and He will tell you what ye used to do. Lo! He knoweth what is in the breasts (of men).

(366) Then worship what ye will beside Him. Say: The losers will be those who lose themselves and their housefolk on the Day of Resurrection. Ah, that will be the manifest loss!

(367) Is he then, who will strike his face against the awful doom upon the Day of Resurrection (as he who doeth right)? And it will be said unto the wrong-doers: Taste what ye used to earn.

(368) They shall have what they will of their Lord's bounty. That is the reward of the good:

(369) That Allah will remit from them the worst of what they did, and will pay them for reward the best they used to do.

(370) Or choose they intercessors other than Allah? Say: what! Even though they have power over nothing and have no intelligence?
