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

(381) Naught is said unto thee (Muhammad) save what was said unto the messengers before thee. Lo! thy Lord is owner of forgiveness, and owner (also) of dire punishment.

(382) And if We had appointed it a Lecture in a foreign tongue they would assuredly have said: If only its verses were expounded (so that we might understand)? what! A foreign tongue and an Arab? - Say unto them (O Muhammad): For those who believe it is a guidance and a healing; and as for those who disbelieve, there is a deafness in their ears, and it is blindness for them. Such are called to from afar.

(383) And in whatsoever ye differ, the verdict therein belongeth to Allah. Such is my Lord, in Whom I put my trust, and unto Whom I turn.

(384) Unto this, then, summon (O Muhammad). And be thou upright as thou art commanded, and follow not their lusts, but say: I believe in whatever scripture Allah hath sent down, and I am commanded to be just among you. Allah is our Lord and your Lord. Unto us our works and unto you your works; no argument between us and you. Allah will bring us together, and unto Him is the journeying.

(385) Thou seest the wrong-doers fearful of that which they have earned, and it will surely befall them, while those who believe and do good works (will be) in flowering meadows of the Gardens, having what they wish from their Lord. This is the great preferment.

(386) Or say they: He hath invented a lie concerning Allah? If Allah willed, He could have sealed thy heart (against them). And Allah will wipe out the lie and will vindicate the truth by His words. Lo! He is Aware of what is hidden in the breasts (of men).

(387) And He it is Who accepteth repentance from His bondmen, and pardoneth the evil deeds, and knoweth what ye do,

(388) And of His portents is the creation of the heaven and the earth, and of whatever beasts He hath dispersed therein. And He is Able to gather them when He will.

(389) whatever of misfortune striketh you, it is what your right hands have earned. And He forgiveth much.

(390) Now whatever ye have been given is but a passing comfort for the life of the world, and that which Allah hath is better and more lasting for those who believe and put their trust in their Lord,
