(3) باب مَا جَاءَ فِي السَّتْرِ عَلَى الْمُسْلِمِ .
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."
