The word(s) "which" appears 877 time(s) in 758 verse(s) in Quran in Mohsin Khan translation.

(491) So as to be ungrateful for the graces which We have bestowed on them. Then enjoy (your short life); but you will come to know.

(492) Or have We revealed to them an authority (a Scripture), which speaks of that which they have been associating with Him?

(493) And that which you give in gift (to others), in order that it may increase (your wealth by expecting to get a better one in return) from other people's property, has no increase with Allah; but that which you give in Zakat (sadaqa - charity etc.) seeking Allah's Countenance, then those, they shall have manifold increase.

(494) Evil (sins and disobedience to Allah) has appeared on land and sea because of what the hands of men have earned (by oppression and evil deeds), that He (Allah) may make them taste a part of that which they have done, in order that they may return (by repenting to Allah, and begging His Pardon).

(495) So set you (O Muhammad صلى الله عليه وسلم) your face (in obedience to Allah, your Lord) to the straight and right religion (Islamic Monotheism), before there comes from Allah a Day which none can avert. On that Day men shall be divided [(in two groups), a group in Paradise and a group in Hell].

(496) And if We send a wind [which would spoil the green growth (tilth) brought up by the previous rain], and they see (their tilth) turn yellow - behold, they then (after their being glad,) would become unthankful (to their Lord Allah as) disbelievers. [Tafsir At-Tabari]

(497) Thus does Allah seal up the hearts of those who know not [the proofs and evidence of the Oneness of Allah i.e. those who try not to understand true facts that which you (Muhammad صلى الله عليه وسلم) have brought to them].

(498) So be patient (O Muhammad صلى الله عليه وسلم). Verily, the Promise of Allah is true; and let not those who have no certainty of faith, discourage you from conveying Allah's Message (which you are obliged to convey).

(499) This is the creation of Allah. So show Me that which those (whom you worship) besides Him have created. Nay, the Zalimun (polytheists, wrongdoers and those who do not believe in the Oneness of Allah) are in plain error.

(500) But if they (both) strive with you to make you join in worship with Me others that of which you have no knowledge, then obey them not; but behave with them in the world kindly, and follow the path of him who turns to Me in repentance and in obedience. Then to Me will be your return, and I shall tell you what you used to do.
