The word(s) "but" appears 1287 time(s) in 1137 verse(s) in Quran in Mohsin Khan translation.

(651) Truly, Allah defends those who believe. Verily, Allah likes not any treacherous ingrate to Allah [those who disobey Allah but obey Shaitan (Satan)].

(652) And the dwellers of Madyan (Midian); and belied was Musa (Moses). but I granted respite to the disbelievers for a while, then I seized them, and how (terrible) was My punishment (against their wrong-doing)!

(653) Have they not travelled through the land, and have they hearts wherewith to understand and ears wherewith to hear? Verily, it is not the eyes that grow blind, but it is the hearts which are in the breasts that grow blind.

(654) but those who strive against Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), to frustrate them, they will be dwellers of the Hell-fire.

(655) Never did We send a Messenger or a Prophet before you but when he did recite the revelation or narrated or spoke, Shaitan (Satan) threw (some falsehood) in it. but Allah abolishes that which Shaitan (Satan) throws in. Then Allah establishes His Revelations. And Allah is All-Knower, All-Wise:

(656) For every nation We have ordained religious ceremonies [e.g. slaughtering of the cattle during the three days of stay at Mina (Makkah) during the Hajj (pilgrimage)] which they must follow; so let them (the pagans) not dispute with you on the matter (i.e. to eat of the cattle which you slaughter, and not to eat of the cattle which Allah kills by its natural death), but invite them to your Lord. Verily you (O Muhammad صلى الله عليه وسلم) indeed are on the (true) straight guidance (i.e. the true religion of Islamic Monotheism).

(657) but whoever seeks beyond that, then those are the transgressors;

(658) And indeed We sent Nuh (Noah) to his people, and he said: "O my people! Worship Allah! You have no other Ilah (God) but Him (Islamic Monotheism). Will you not then be afraid (of Him i.e. of His punishment because of worshipping others besides Him)?"

(659) but the chiefs of his people who disbelieved said: "He is no more than a human being like you, he seeks to make himself superior to you. Had Allah willed, He surely could have sent down angels. Never did we hear such a thing among our fathers of old.

(660) And We sent to them a Messenger from among themselves (saying): "Worship Allah! You have no other Ilah (God) but Him. Will you not then be afraid (of Him i.e. of His punishment because of worshipping others besides Him)?"
