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

(141) Or deemed ye that ye would be left (in peace) when Allah yet knoweth not those of you who strive, choosing for familiar none save Allah and His messenger and the believers? Allah is Informed of what ye do.

(142) On the day when it will (all) be heated in the fire of hell, and their foreheads and their flanks and their backs will be branded therewith (and it will be said unto them): Here is that which ye hoarded for yourselves. Now taste of what ye used to hoard.

(143) O ye who believe! what aileth you that when it is said unto you: Go forth in the way of Allah, ye are bowed down to the ground with heaviness. Take ye pleasure in the life of the world rather than in the Hereafter? The comfort of the life of the world is but little in the Hereafter.

(144) The hypocrites fear lest a surah should be revealed concerning them, proclaiming what is in their hearts. Say: Scoff (your fill)! Lo! Allah is disclosing what ye fear.

(145) Then let them laugh a little: they will weep much, as the reward of what they used to earn.

(146) They will make excuse to you (Muslims) when ye return unto them. Say: Make no excuse, for we shall not believe you. Allah hath told us tidings of you. Allah and His messenger will see your conduct, and then ye will be brought back unto Him Who knoweth the Invisible as well as the Visible, and He will tell you what ye used to do.

(147) They will swear by Allah unto you, when ye return unto them, that ye may let them be. Let them be, for lo! they are unclean, and their abode is hell as the reward for what they used to earn.

(148) And say (unto them): Act! Allah will behold your actions, and (so will) His messenger and the believers, and ye will be brought back to the Knower of the Invisible and the Visible, and He will tell you what ye used to do.

(149) It was never Allah's (part) that He should send a folk astray after He had guided them until He had made clear unto them what they should avoid. Lo! Allah is Aware of all things.

(150) Nor spend they any spending, small or great, nor do they cross a valley, but it is recorded for them, that Allah may repay them the best of what they used to do.
