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

(741) He said: "I intend to wed one of these two daughters of mine to you, on condition that you serve me for eight years; but if you complete ten years, it will be (a favour) from you. but I intend not to place you under a difficulty. If Allah wills, you will find me one of the righteous."

(742) "And throw your stick!" but when he saw it moving as if it were a snake, he turned in flight, and looked not back. (It was said:) "O Musa (Moses)! Draw near, and fear not. Verily, you are of those who are secure.

(743) Then when Musa (Moses) came to them with Our Clear Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), they said: "This is nothing but invented magic. Never did we hear of this among our fathers of old."

(744) but We created generations [after generations i.e. after Musa (Moses) عليه السلام], and long were the ages that passed over them. And you (O Muhammad صلى الله عليه وسلم) were not a dweller among the people of Madyan (Midian), reciting Our Verses to them. but it is We Who kept sending (Messengers).

(745) And you (O Muhammad صلى الله عليه وسلم) were not at the side of the Tur (Mount) when We did call: [it is said that Allah called the followers of Muhammad صلى الله عليه وسلم, and they answered His Call, or that Allah called Musa (Moses)]. but (you are sent) as a mercy from your Lord, to give warning to a people to whom no warner had come before you: in order that they may remember or receive admonition. [Tafsir At-Tabari].

(746) but when the truth (i.e. Muhammad صلى الله عليه وسلم with his Message) has come to them from Us, they say: "Why is he not given the like of what was given to Musa (Moses)? Did they not disbelieve in that which was given to Musa (Moses) of old? They say: "Two kinds of magic [the Taurat (Torah) and the Qur'an], each helping the other!" And they say: "Verily in both we are disbelievers."

(747) but if they answer you not (i.e. do not bring the Book nor believe in your doctrine of Islamic Monotheism), then know that they only follow their own lusts. And who is more astray than one who follows his own lusts, without guidance from Allah? Verily Allah guides not the people who are Zalimun (wrong-doers, disobedient to Allah, and polytheists).

(748) Verily you (O Muhammad صلى الله عليه وسلم) guide not whom you like, but Allah guides whom He wills. And He knows best those who are the guided.

(749) And they say: "If we follow the guidance with you, we would be snatched away from our land." Have We not established for them a secure sanctuary (Makkah), to which are brought fruits of all kinds, a provision from Ourselves, but most of them know not.

(750) And it will be said (to them): "Call upon your (so-called) partners (of Allah)", and they will call upon them, but they will give no answer to them, and they will see the torment. (They will then wish) if only they had been guided!
