The word(s) "thou" appears 961 time(s) in 726 verse(s) in Quran in Muhammad Pickthal translation.

(321) Or deemest thou that the People of the Cave and the Inscription are a wonder among Our portents?

(322) These, our people, have chosen (other) gods beside Him though they bring no clear warrant (vouchsafed) to them. And who doth greater wrong than he who inventeth a lie concerning Allah?

(323) And thou mightest have seen the sun when it rose move away from their cave to the right, and when it set go past them on the left, and they were in the cleft thereof. That was (one) of the portents of Allah. He whom Allah guideth, he indeed is led aright, and he whom He sendeth astray, for him thou wilt not find a guiding friend.

(324) And thou wouldst have deemed them waking though they were asleep, and We caused them to turn over to the right and the left, and their dog stretching out his paws on the threshold. If thou hadst observed them closely thou hadst assuredly turned away from them in flight, and hadst been filled with awe of them.

(325) Except if Allah will. And remember thy Lord when thou forgettest, and say: It may be that my Lord guideth me unto a nearer way of truth than this.

(326) And recite that which hath been revealed unto thee of the Scripture of thy Lord. There is none who can change His words, and thou wilt find no refuge beside Him.

(327) His comrade, when he (thus) spake with him, exclaimed: Disbelievest thou in Him Who created thee of dust, then of a drop (of seed), and then fashioned thee a man?

(328) If only, when thou enteredst thy garden, thou hadst said: That which Allah willeth (will come to pass)! There is no strength save in Allah! though thou seest me as less than thee in wealth and children,

(329) Or some morning the water thereof will be lost in the earth so that thou canst not make search for it.

(330) And they are set before thy Lord in ranks (and it is said unto them): Now verily have ye come unto Us as We created you at the first. But ye thought that We had set no tryst for you.
