The word(s) "which" appears 700 time(s) in 620 verse(s) in Quran in Muhammad Habib Shakir translation.

(571) O Prophet! why do you forbid (yourself) that which Allah has made lawful for you; you seek to please your wives; and Allah is Forgiving, Merciful.

(572) O you who believe! turn to Allah a sincere turning; maybe your Lord will remove from you your evil and cause you to enter gardens beneath which rivers flow, on the day on which Allah will not abase the Prophet and those who believe with him; their light shall run on before them and on their right hands; they shall say: Our Lord! make perfect for us our light, and grant us protection, surely Thou hast power over all things.

(573) Who created death and life that He may try you-- which of you is best in deeds; and He is the Mighty, the Forgiving,

(574) But when they shall see it nigh, the faces of those who disbelieve shall be sorry, and it shall be said; This is that which you used to call for.

(575) which of you is afflicted with madness.

(576) Ask them which of them will vouch for that,

(577) which He made to prevail against them for seven nights and eight days unremittingly, so that you might have seen the people therein prostrate as if they were the trunks of hollow palms.

(578) The fruits of which are near at hand:

(579) Then thrust him into a chain the length of which is seventy cubits.

(580) which none but the wrongdoers eat.
