Abu Salamah (may Allah have mercy on him) says that once I asked Hazrat Aisha (may Allah be pleased with her) about the bath of the Prophet (peace and blessings be upon him), so she said that the Prophet (peace and blessings be upon him) would first wash his both hands, then wash his private parts, then wash his hands again and rinse his mouth, put water in his nose and pour water over his head, then pour water over his entire body.
