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

(871) "We have not heard (the like) of this in the religion of these later days (i.e. Christianity). This is nothing but an invention! [Tafsir Al-Qurtubi]

(872) "Has the Reminder been sent down to him (alone) from among us?" Nay, but they are in doubt about My Reminder (this Qur'an)! Nay, but they have not tasted (My) Torment!

(873) Not one of them but belied the Messengers; therefore My Torment was justified,

(874) Say (O Muhammad صلى الله عليه وسلم): "I am only a warner and there is no Ilah (God) except Allah (none has the right to be worshipped but Allah) the One, the Irresistible,

(875) Had Allah willed to take a son (or offspring), He could have chosen whom He willed out of those whom He created. but glory be to Him! (He is above such things). He is Allah, the One, the Irresistible .

(876) He created you (all) from a single person (Adam); then made from him his wife [Hawwa' (Eve)]. And He has sent down for you of cattle eight pairs (of the sheep, two, male and female; of the goats, two, male and female; of the oxen, two, male and female; and of the camels, two, male and female). He creates you in the wombs of your mothers: creation after creation in three veils of darkness. Such is Allah your Lord. His is the kingdom. La ilaha illa Huwa (none has the right to be worshipped but He). How then are you turned away?

(877) And when some hurt touches man, he cries to his Lord (Allah Alone), turning to Him in repentance. but when He bestows a favour upon him from Himself, he forgets that for which he cried for before, and he sets up rivals to Allah, in order to mislead others from His Path. Say: "Take pleasure in your disbelief for a while: surely you are (one) of the dwellers of the Fire!"

(878) Those who listen to the Word [good advice La ilaha illallah - (none has the right to be worshipped but Allah) and Islamic Monotheism] and follow the best thereof (i.e. worship Allah Alone, repent to Him and avoid Taghut) those are (the ones) whom Allah has guided and those are men of understanding.

(879) but those who fear their Lord (Allah) and keep their duty to Him, for them are built lofty rooms, one above another under which rivers flow (i.e. Paradise). (This is) the Promise of Allah: and Allah does not fail in (His) Promise.

(880) So Allah made them to taste the disgrace in the present life, but greater is the torment of the Hereafter if they only knew!
