English Translation
Muhammad ibn al-Muthanna narrated to us: Abu Dawud narrated to us: Hammam narrated to us from Qatadah from Anas from the Noble Prophet (blessings and peace of Allah be upon him) who stated: «Help your brother whether he is an oppressor or oppressed.» It was said: O Messenger of Allah, we help him when he is oppressed, but how do we help him when he is the oppressor? He said: «You restrain him from oppression.»
