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

(781) Then why did those whom they had chosen for gods as a way of approach (unto Allah) not help them? Nay, but they did fail them utterly. And (all) that was their lie, and what they used to invent.

(782) Then have patience (O Muhammad) even as the stout of heart among the messengers (of old) had patience, and seek not to hasten on (the doom) for them. On the day when they see that which they are promised (it will seem to them) as though they had tarried but an hour of daylight. A clear message. Shall any be destroyed save evil-living folk?

(783) Now when ye meet in battle those who disbelieve, then it is smiting of the necks until, when ye have routed them, then making fast of bonds; and afterward either grace or ransom till the war lay down its burdens. That (is the ordinance). And if Allah willed He could have punished them (without you) but (thus it is ordained) that He may try some of you by means of others. And those who are slain in the way of Allah, He rendereth not their actions vain.

(784) Await they aught save the Hour, that it should come upon them unawares? And the beginnings thereof have already come. but how, when it hath come upon them, can they take their warning?

(785) And those who believe say: If only a surah were revealed! but when a decisive surah is revealed and war is mentioned therein, thou seest those in whose hearts is a disease looking at thee with the look of men fainting unto death. Therefor woe unto them!

(786) The life of the world is but a sport and a pastime. And if ye believe and ward off (evil). He will give you your wages, and will not ask of you your wordly wealth.

(787) Those of the wandering Arabs who were left behind will tell thee: Our possessions and our households occupied us, so ask forgiveness for us! They speak with their tongues that which is not in their hearts. Say: Who can avail you aught against Allah, if He intend you hurt or intend you profit? Nay, but Allah is ever Aware of what ye do.

(788) Nay, but ye deemed that the messenger and the believers would never return to their own folk, and that was made fairseeming in your hearts, and ye did think an evil thought, and ye were worthless folk.

(789) Those who were left behind will say, when ye set forth to capture booty: Let us go with you. They fain would change the verdict of Allah. Say (unto them, O Muhammad): Ye shall not go with us. Thus hath Allah said beforehand. Then they will say: Ye are envious of us. Nay, but they understand not, save a little.

(790) Say unto those of the wandering Arabs who were left behind: Ye will be called against a folk of mighty prowess, to fight them until they surrender; and if ye obey, Allah will give you a fair reward; but if ye turn away as ye did turn away before, He will punish you with a painful doom.
