«لا بأس ولينصر الرجل أخاه ظالما أو مظلوما إن كان ظالما فلينهه فإنه له نصر وإن كان مظلوما فلينصره»
The Prophet (peace and blessings be upon him) said:
"There is no harm; let a man help his brother, whether he is an oppressor or oppressed. If he is an oppressor, let him restrain him from oppression, for that is helping him; and if he is oppressed, let him help him."
