The word(s) "brother" appears 64 time(s) in 58 verse(s) in Quran in Muhammad Habib Shakir translation.

(41) There is no blame on the blind man, nor is there blame on the lame, nor is there blame on the sick, nor on yourselves that you eat from your houses, or your fathers' houses or your mothers' houses, or your brothers' houses, or your sisters' houses, or your paternal uncles' houses, or your paternal aunts' houses, or your maternal uncles' houses, or your maternal aunts' houses, or what you possess the keys of, or your friends' (houses). It is no sin in you that you eat together or separately. So when you enter houses, greet your people with a salutation from Allah, blessed (and) goodly; thus does Allah make clear to you the communications that you may understand.

(42) And certainly We gave Musa the Book and We appointed with him his brother Haroun an aider.

(43) They said: Give him and his brother respite and send heralds into the cities

(44) When their brother Nuh said to them: Will you not guard (against evil)?

(45) When their brother Hud said to them: Will you not guard (against evil)?

(46) When their brother Salih said to them: Will you not guard (against evil)?

(47) When their brother Lut said to them: Will you not guard (against evil)?

(48) And certainly We sent to Samood their brother Salih, saying: Serve Allah; and lo! they became two sects quarrelling with each other.

(49) And my brother, Haroun, he is more eloquent of tongue than I, therefore send him with me as an aider, verifying me: surely I fear that they would reject me.

(50) He said: We will strengthen your arm with your brother, and We will give you both an authority, so that they shall not reach you; (go) with Our signs; you two and those who follow you shall be uppermost.
