The word(s) "brotherhood" appears 3 time(s) in 2 verse(s) in Quran in Mohsin Khan translation.

(1) And to everyone, We have appointed heirs of that (property) left by parents and relatives. To those also with whom you have made a pledge (brotherhood), give them their due portion (by Wasiyyah - will) . Truly, Allah is Ever a Witness over all things.

(2) The Prophet is closer to the believers than their ownselves, and his wives are their (believers') mothers (as regards respect and marriage). And blood relations among each other have closer personal ties in the Decree of Allah (regarding inheritance) than (the brotherhood of) the believers and the Muhajirun (emigrants from Makkah), except that you do kindness to those brothers (when the Prophet صلى الله عليه وسلم joined them in brotherhood ties). This has been written in the (Allah's Book of Divine) Decrees - (Al-Lauh Al-Mahfuz)."
