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

(11) but those who disbelieve and belie Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) - such are the dwellers of the Fire. They shall abide therein forever.

(12) O Children of Israel! Remember My Favour which I bestowed upon you, and fulfil (your obligations to) My Covenant (with you) so that I fulfil (My Obligations to) your covenant (with Me), and fear none but Me.

(13) And (remember) when you said: "O Musa (Moses)! We shall never believe in you until we see Allah plainly." but you were seized with a thunder-bolt (lightning) while you were looking.

(14) And We shaded you with clouds and sent down on you Al-Manna and the quails, (saying): "Eat of the good lawful things We have provided for you," (but they rebelled). And they did not wrong Us but they wronged themselves.

(15) but those who did wrong changed the word from that which had been told to them for another, so We sent upon the wrong-doers Rijz (a punishment) from the heaven because of their rebelling against Allah's obedience. (Tafsir At-Tabari).

(16) They said, "Call upon your Lord for us that He may make plain to us what it is!" He said, "He says, 'Verily, it is a cow neither too old nor too young, but (it is) between the two conditions', so do what you are commanded."

(17) And (remember) when you killed a man and fell into dispute among yourselves as to the crime. but Allah brought forth that which you were hiding.

(18) And when they (Jews) meet those who believe (Muslims), they say, "We believe", but when they meet one another in private, they say, "Shall you (Jews) tell them (Muslims) what Allah has revealed to you [Jews, about the description and the qualities of Prophet Muhammad صلى الله عليه وسلم, that which are written in the Taurat (Torah)] , that they (Muslims) may argue with you (Jews) about it before your Lord?" Have you (Jews) then no understanding?

(19) And there are among them (Jews) unlettered people, who know not the Book, but they trust upon false desires and they but guess.

(20) And they (Jews) say, "The Fire (i.e. Hell-fire on the Day of Resurrection) shall not touch us but for a few numbered days." Say (O Muhammad صلى الله عليه وسلم to them): "Have you taken a covenant from Allah, so that Allah will not break His Covenant? Or is it that you say of Allah what you know not?"
