The word(s) "which" appears 958 time(s) in 806 verse(s) in Quran in Muhammad Pickthal translation.

(321) Lo! now they fold up their breasts that they may hide (their thoughts) from Him. At the very moment when they cover themselves with their clothing, Allah knoweth that which they keep hidden and that which they proclaim. Lo! He is Aware of what is in the breasts (of men).

(322) And He it is Who created the heavens and the earth in six Days - and His Throne was upon the water - that He might try you, which of you is best in conduct. Yet if thou (O Muhammad) sayest: Lo! ye will be raised again after death! those who disbelieve will surely say: This is naught but mere magic.

(323) And if We delay for them the doom until a reckoned time, they will surely say: What withholdeth it? Verily on the day when it cometh unto them, it cannot be averted from them, and that which they derided will surround them.

(324) A likely thing, that thou wouldst forsake aught of that which hath been revealed unto thee, and that thy breast should be straitened for it, because they say: Why hath not a treasure been sent down for him, or an angel come with him? Thou art but a warner, and Allah is in charge of all things.

(325) Such are they who have lost their souls, and that which they used to invent hath failed them.

(326) This is of the tidings of the Unseen which We inspire in thee (Muhammad). Thou thyself knewest it not, nor did thy folk (know it) before this. Then have patience. Lo! the sequel is for those who ward off (evil).

(327) They said: O Salih! Thou hast been among us hitherto as that wherein our hope was placed. Dost thou ask us not to worship what our fathers worshipped? Lo! we verily are in grave doubt concerning that to which thou callest us.

(328) (It was said) O Abraham! Forsake this! Lo! thy Lord's commandment hath gone forth, and lo! there cometh unto them a doom which cannot be repelled.

(329) (The messengers) said: O Lot! Lo! we are messengers of thy Lord; they shall not reach thee. So travel with thy people in a part of the night, and let not one of you turn round - (all) save thy wife. Lo! that which smiteth them will smite her (also). Lo! their tryst is (for) the morning. Is not the morning nigh?

(330) That which Allah leaveth with you is better for you if ye are believers; and I am not a keeper over you.
