Abu Salamah bin Abdur Rahman narrates: I heard the noble wife of the Prophet (peace be upon him), Sayyida Umm Salamah (may Allah be pleased with her), saying: She said: I heard the Prophet (peace be upon him) saying: "When the skin of a dead animal is tanned, then there is no harm in using it; there is no harm in using its wool, its hair, or its horns, when they are washed with water." The narrator of this narration, Yusuf bin Safar, is abandoned, and no other narration is transmitted from him except this narration (or only he has transmitted this narration).
