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

(41) Verily, those who conceal what Allah has sent down of the Book, and purchase a small gain therewith (of worldly things), they eat into their bellies nothing but fire. Allah will not speak to them on the Day of Resurrection, nor purify them, and theirs will be a painful torment.

(42) It is not Al-Birr (piety, righteousness, and each and every act of obedience to Allah, etc.) that you turn your faces towards east and (or) west (in prayers); but Al-Birr is (the quality of) the one who believes in Allah, the Last Day, the Angels, the Book, the Prophets and gives his wealth, in spite of love for it, to the kinsfolk, to the orphans, and to Al-Masakin (the poor), and to the wayfarer, and to those who ask, and to set slaves free, performs As-Salat (Iqamat-as-Salat ), and gives the Zakat, and who fulfil their covenant when they make it, and who are patient in extreme poverty and ailment (disease) and at the time of fighting (during the battles). Such are the people of the truth and they are Al-Muttaqun (the pious - See V.2:2).

(43) O you who believe! Al-Qisas (the Law of Equality in punishment) is prescribed for you in case of murder: the free for the free, the slave for the slave, and the female for the female. but if the killer is forgiven by the brother (or the relatives, etc.) of the killed against blood-money, then adhering to it with fairness and payment of the blood-money to the heir should be made in fairness. This is an alleviation and a mercy from your Lord. So after this whoever transgresses the limits (i.e. kills the killer after taking the blood-money), he shall have a painful torment.

(44) but he who fears from a testator some unjust act or wrong-doing, and thereupon he makes peace between the parties concerned, there shall be no sin on him. Certainly, Allah is Oft-Forgiving, Most Merciful.

(45) [Observing Saum (fasts)] for a fixed number of days, but if any of you is ill or on a journey, the same number (should be made up) from other days. And as for those who can fast with difficulty, (e.g. an old man), they have (a choice either to fast or) to feed a Miskin (poor person) (for every day). but whoever does good of his own accord, it is better for him. And that you fast is better for you if only you know.

(46) They ask you (O Muhammad صلى الله عليه وسلم) about the new moons. Say: These are signs to mark fixed periods of time for mankind and for the pilgrimage. It is not Al-Birr (piety, righteousness) that you enter the houses from the back but Al-Birr (is the quality of the one) who fears Allah. So enter houses through their proper doors, and fear Allah that you may be successful.

(47) And fight in the Way of Allah those who fight you, but transgress not the limits. Truly, Allah likes not the transgressors. [This Verse is the first one that was revealed in connection with Jihad, but it was supplemented by another (9:36)].

(48) And kill them wherever you find them, and turn them out from where they have turned you out. And Al-Fitnah is worse than killing. And fight not with them at Al-Masjid-Al-Haram (the sanctuary at Makkah), unless they (first) fight you there. but if they attack you, then kill them. Such is the recompense of the disbelievers.

(49) but if they cease, then Allah is Oft-Forgiving, Most Merciful.

(50) And fight them until there is no more Fitnah (disbelief and worshipping of others along with Allah) and (all and every kind of) worship is for Allah (Alone). but if they cease, let there be no transgression except against Az-Zalimun (the polytheists, and wrong-doers)
