Sayyiduna Abu Najeeh Salimi (may Allah be pleased with him) narrates: We were besieging Ta’if along with the Prophet (peace and blessings of Allah be upon him). I heard the Prophet (peace and blessings of Allah be upon him) say: “Whoever among the Muslims frees a Muslim, Allah Almighty will, in exchange for every bone of the freed person, protect every bone of the one who freed him from Hell. And if a Muslim woman frees a Muslim woman, Allah Almighty will, in exchange for every bone of the freed woman, protect every bone of the one who freed her from Hell.” The Sheikh states: Abu Najeeh’s name is Amr bin Abasah.
