The word(s) "which" appears 609 time(s) in 551 verse(s) in Quran in Abdullah Yusuf Ali translation.

(211) Nor take life - which Allah has made sacred - except for just cause. And if anyone is slain wrongfully, we have given his heir authority (to demand qisas or to forgive): but let him not exceed bounds in the matter of taking life; for he is helped (by the Law).

(217) We send down (stage by stage) in the Qur'an that which is a healing and a mercy to those who believe: to the unjust it causes nothing but loss after loss.

(219) See they not that Allah, Who created the heavens and the earth, has power to create the like of them (anew)? Only He has decreed a term appointed, of which there is no doubt. But the unjust refuse (to receive it) except with ingratitude.

(220) (It is) a Qur'an which We have divided (into parts from time to time), in order that thou mightest recite it to men at intervals: We have revealed it by stages.
