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

(121) He said: what hindered thee that thou didst not fall prostrate when I bade thee? (Iblis) said: I am better than him. Thou createdst me of fire while him Thou didst create of mud.

(122) And the first of them saith unto the last of them: Ye were no whit better than us, so taste the doom for what ye used to earn.

(123) And We remove whatever rancour may be in their hearts. Rivers flow beneath them. And they say: The praise to Allah, Who hath guided us to this. We could not truly have been led aright if Allah had not guided us. Verily the messengers of our Lord did bring the Truth. And it is cried unto them: This is the Garden. Ye inherit it for what ye used to do.

(124) And the dwellers on the Heights call unto men whom they know by their marks, (saying): what did your multitude and that in which ye took your pride avail you?

(125) They said: Hast come unto us that we should serve Allah alone, and forsake what our fathers worshipped? Then bring upon us that wherewith thou threatenest us if thou art of the truthful!

(126) And if the people of the townships had believed and kept from evil, surely We should have opened for them blessings from the sky and from the earth. But (unto every messenger) they gave the lie, and so We seized them on account of what they used to earn.

(127) Who would expel you from your land. Now what do ye advise?

(128) And they said: whatever portent thou bringest wherewith to bewitch us, we shall not put faith in thee.

(129) Those who deny Our revelations and the meeting of the Hereafter, their works are fruitless. Are they requited aught save what they used to do?

(130) Allah's are the fairest names. Invoke Him by them. And leave the company of those who blaspheme His names. They will be requited what they do.
