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

(71) Verily, you are those who have disputed about that of which you have knowledge. Why do you then dispute concerning that of which you have no knowledge? It is Allah Who knows, and you know not.

(72) And a party of the people of the Scripture say: "Believe in the morning in that which is revealed to the believers (Muslims), and reject it at the end of the day, so that they may turn back.

(73) And believe no one except the one who follows your religion. Say (O Muhammad صلى الله عليه وسلم): "Verily! Right guidance is the Guidance of Allah" and do not believe that anyone can receive like that which you have received, otherwise they would engage you in argument before your Lord. Say (O Muhammad صلى الله عليه وسلم): "All the bounty is in the Hand of Allah; He grants to whom He wills. And Allah is All-Sufficient for His creatures' needs, All-Knower."

(74) And (remember) when Allah took the Covenant of the Prophets, saying: "Take whatever I gave you from the Book and Hikmah (understanding of the Laws of Allah), and afterwards there will come to you a Messenger (Muhammad صلى الله عليه وسلم) confirming what is with you; you must, then, believe in him and help him." Allah said: "Do you agree (to it) and will you take up My Covenant (which I conclude with you)?" They said: "We agree." He said: "Then bear witness; and I am with you among the witnesses (for this)."

(75) By no means shall you attain Al-Birr (piety, righteousness - here it means Allah's Reward, i.e. Paradise), unless you spend (in Allah's Cause) of that which you love; and whatever of good you spend, Allah knows it well.

(76) Surely, those who reject Faith (disbelieve in Allah and in Muhammad صلى الله عليه وسلم) as being Allah's Messenger and in all that which he صلى الله عليه وسلم has brought from Allah), neither their properties, nor their offspring will avail them aught against Allah. They are the dwellers of the Fire, therein they will abide. (Tafsir At-Tabari).

(77) The likeness of what they spend in this world is the likeness of a wind which is extremely cold; it struck the harvest of a people who did wrong against themselves and destroyed it, (i.e. the good deed of a person is only accepted if he is a monotheist and believes in all the Prophets of Allah, including the Christ عليه السلام and Muhammad صلى الله عليه وسلم). Allah wronged them not, but they wronged themselves.

(78) And fear the Fire, which is prepared for the disbelievers.

(79) And march forth in the way (which leads to) forgiveness from your Lord, and for Paradise as wide as the heavens and the earth, prepared for Al-Muttaqun (the pious - See V.2:2).

(80) And many a Prophet (i.e. many from amongst the Prophets) fought (in Allah's Cause) and along with him (fought) large bands of religious learned men. But they never lost heart for that which did befall them in Allah's Way, nor did they weaken nor degrade themselves. And Allah loves As-Sabirun (the patient).
