Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) says that a man brought his daughter to the Prophet (peace and blessings be upon him) and said: "O Messenger of Allah (peace and blessings be upon him)! This daughter of mine has refused to marry." The Prophet (peace and blessings be upon him) said: "Obey your father." She said: "By the One who sent you with the truth! I will not marry until you tell me what the right of the husband over his wife is." He (peace and blessings be upon him) said: "The right of the husband over his wife is such that if the husband had a sore and his wife licked it clean, she still would not have fulfilled his right."
