The word(s) "brother's" appears 6 time(s) in 4 verse(s) in Quran in Muhammad Pickthal translation.

(1) Forbidden unto you are your mothers, and your daughters, and your sisters, and your father's sisters, and your mother's sisters, and your brother's daughters and your sister's daughters, and your foster-mothers, and your foster-sisters, and your mothers-in-law, and your step-daughters who are under your protection (born) of your women unto whom ye have gone in - but if ye have not gone in unto them, then it is no sin for you (to marry their daughters) - and the wives of your sons who (spring) from your own loins. And (it is forbidden unto you) that ye should have two sisters together, except what hath already happened (of that nature) in the past. Lo! Allah is ever Forgiving, Merciful.

(2) Then Allah sent a raven scratching up the ground, to show him how to hide his brother's naked corpse. He said: Woe unto me! Am I not able to be as this raven and so hide my brother's naked corpse? And he became repentant.

(3) And when he provided them with their provision, he put the drinking-cup in his brother's saddlebag, and then a crier cried: O camel-riders! Lo! ye are surely thieves!

(4) Then he (Joseph) began the search with their bags before his brother's bag, then he produced it from his brother's bag. Thus did We contrive for Joseph. He could not have taken his brother according to the king's law unless Allah willed. We raise by grades (of mercy) whom We will, and over every lord of knowledge there is one more knowing.
