Mas'ar bin Kadam مسعر بن كدام · The Book on Legal Punishments (Al-Hudud)

That the Messenger of Allah (ﷺ) said: "Whoever relieves a Muslim of a burden from the burdens of the world, Allah will relieve him of a burden from the burdens of the Hereafter. And whoever covers (the faults of) a Muslim, Allah will cover (his faults) for him in the world and the Hereafter. And Allah is engaged in helping the worshipper as long as the worshipper is engaged in helping his brother."
