Chapter 17: The Book on Legal Punishments (Al-Hudud)
Narrated Ibn 'Umar: That the Messenger of Allah (ﷺ) said: "The Muslim is the brother of the Muslim, he doesn' t oppress him and doesn' t put him into ruin, and whoever is concerned for the needs of his brother, Allah is concerned for his needs, and whoever relieves a Muslim of a burden, Allah will relieve him of a burden from the burdens of the Day of Judgement and whoever covers (the faults of) a Muslim, Allah will cover (his faults) on the Day of Judgement."
