The word(s) "but" appears 1022 time(s) in 947 verse(s) in Quran in Muhammad Pickthal translation.

(11) but those who did wrong changed the word which had been told them for another saying, and We sent down upon the evil-doers wrath from heaven for their evil-doing.

(12) And when they fall in with those who believe, they say: We believe. but when they go apart one with another they say: Prate ye to them of that which Allah hath disclosed to you that they may contend with you before your Lord concerning it? Have ye then no sense?

(13) Among them are unlettered folk who know the Scripture not except from hearsay. They but guess.

(14) Nay, but whosoever hath done evil and his sin surroundeth him; such are rightful owners of the Fire; they will abide therein.

(15) And they say: Our hearts are hardened. Nay, but Allah hath cursed them for their unbelief. Little is that which they believe.

(16) but they will never long for it, because of that which their own hands have sent before them. Allah is aware of evil-doers.

(17) And follow that which the devils falsely related against the kingdom of Solomon. Solomon disbelieved not; but the devils disbelieved, teaching mankind magic and that which was revealed to the two angels in Babel, Harut and Marut. Nor did they (the two angels) teach it to anyone till they had said: We are only a temptation, therefore disbelieve not (in the guidance of Allah). And from these two (angles) people learn that by which they cause division between man and wife; but they injure thereby no-one save by Allah's leave. And they learn that which harmeth them and profiteth them not. And surely they do know that he who trafficketh therein will have no (happy) portion in the Hereafter; and surely evil is the price for which they sell their souls, if they but knew.

(18) O ye who believe, say not (unto the Prophet): "Listen to us" but say "Look upon us," and be ye listeners. For disbelievers is a painful doom.

(19) Neither those who disbelieve among the people of the Scripture nor the idolaters love that there should be sent down unto you any good thing from your Lord. but Allah chooseth for His mercy whom He will, and Allah is of Infinite Bounty.

(20) Nothing of our revelation (even a single verse) do we abrogate or cause be forgotten, but we bring (in place) one better or the like thereof. Knowest thou not that Allah is Able to do all things?
