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

(321) And We divided them into twelve tribes (as distinct) nations. We revealed to Musa (Moses) when his people asked him for water (saying): "Strike the stone with your stick", and there gushed forth out of it twelve springs, each group knew its own place for water. We shaded them with the clouds and sent down upon them Al-Manna and the quails (saying): "Eat of the good things with which We have provided you." They harmed Us not but they used to harm themselves.

(322) but those among them who did wrong changed the word that had been told to them. So We sent on them a torment from the heaven in return for their wrong-doings.

(323) So when they forgot the remindings that had been given to them, We rescued those who forbade evil, but We seized those who did wrong with a severe torment because they used to rebel against Allah's Command (disobey Allah).

(324) And (remember) when your Lord declared that He would certainly keep on sending against them (i.e. the Jews), till the Day of Resurrection, those who would afflict them with a humiliating torment. Verily, your Lord is Quick in Retribution (for the disobedient, wicked) and certainly He is Oft-Forgiving, Most Merciful (for the obedient and those who beg Allah's Forgiveness).

(325) Then after them succeeded an (evil) generation, which inherited the Book, but they chose (for themselves) the goods of this low life (evil pleasures of this world) saying (as an excuse): "(Everything) will be forgiven to us." And if (again) the offer of the like (evil pleasures of this world) came their way, they would (again) seize them (would commit those sins). Was not the covenant of the Book taken from them that they would not say about Allah anything but the truth? And they have studied what is in it (the Book). And the home of the Hereafter is better for those who are Al-Muttaqun (the pious - See V.2:2). Do not you then understand?

(326) And recite (O Muhammad صلى الله عليه وسلم) to them the story of him to whom We gave Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), but he threw them away; so Shaitan (Satan) followed him up, and he became of those who went astray.

(327) And had We willed, We would surely have elevated him therewith but he clung to the earth and followed his own vain desire. So his parable is the parable of a dog: if you drive him away, he lolls his tongue out, or if you leave him alone, he (still) lolls his tongue out. Such is the parable of the people who reject Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.). So relate the stories, perhaps they may reflect.

(328) Do they not reflect? There is no madness in their companion (Muhammad صلى الله عليه وسلم). He is but a plain warner.

(329) They ask you about the Hour (Day of Resurrection): "When will be its appointed time?" Say: "The knowledge thereof is with my Lord (Alone). None can reveal its time but He. Heavy is its burden through the heavens and the earth. It shall not come upon you except all of a sudden." They ask you as if you have a good knowledge of it. Say: "The knowledge thereof is with Allah (Alone), but most of mankind know not."

(330) Say (O Muhammad صلى الله عليه وسلم): "I possess no power over benefit or harm to myself except as Allah wills. If I had the knowledge of the Ghaib (Unseen), I should have secured for myself an abundance of wealth, and no evil should have touched me. I am but a warner, and a bringer of glad tidings unto people who believe."
