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

(61) And let not those who hoard up that which Allah hath bestowed upon them of His bounty think that it is better for them. Nay, it is worse for them. That which they hoard will be their collar on the Day of Resurrection. Allah's is the heritage of the heavens and the earth, and Allah is Informed of what ye do.

(62) Think not that those who exult in what they have given, and love to be praised for what they have not done - Think not, they are in safety from the doom. A painful doom is theirs.

(63) Give not unto the foolish (what is in) your (keeping of their) wealth, which Allah hath given you to maintain; but feed and clothe them from it, and speak kindly unto them.

(64) And marry not those women whom your fathers married, except what hath already happened (of that nature) in the past. Lo! it was ever lewdness and abomination, and an evil way.

(65) Forbidden unto you are your mothers, and your daughters, and your sisters, and your father's sisters, and your mother's sisters, and your brother's daughters and your sister's daughters, and your foster-mothers, and your foster-sisters, and your mothers-in-law, and your step-daughters who are under your protection (born) of your women unto whom ye have gone in - but if ye have not gone in unto them, then it is no sin for you (to marry their daughters) - and the wives of your sons who (spring) from your own loins. And (it is forbidden unto you) that ye should have two sisters together, except what hath already happened (of that nature) in the past. Lo! Allah is ever Forgiving, Merciful.

(66) And all married women (are forbidden unto you) save those (captives) whom your right hands possess. It is a decree of Allah for you. Lawful unto you are all beyond those mentioned, so that ye seek them with your wealth in honest wedlock, not debauchery. And those of whom ye seek content (by marrying them), give unto them their portions as a duty. And there is no sin for you in what ye do by mutual agreement after the duty (hath been done). Lo! Allah is ever Knower, Wise.

(67) what have they (to fear) if they believe in Allah and the Last Day and spend (aright) of that which Allah hath bestowed upon them, when Allah is ever Aware of them (and all they do)?

(68) O ye unto whom the Scripture hath been given! Believe in what We have revealed confirming that which ye possess, before We destroy countenances so as to confound them, or curse them as We cursed the Sabbath-breakers (of old time). The commandment of Allah is always executed.

(69) But nay, by thy Lord, they will not believe (in truth) until they make thee judge of what is in dispute between them and find within themselves no dislike of that which thou decidest, and submit with full submission.

(70) And if We had decreed for them: Lay down your lives or go forth from your dwellings, but few of them would have done it; though if they did what they are exhorted to do it would be better for them, and more strengthening;
