Ata bin Yasar (may Allah have mercy on him) said that a man asked the Prophet (peace and blessings be upon him): Should I ask permission even from my mother? He (peace and blessings be upon him) said: "Yes!" The man said: I live with her. He (peace and blessings be upon him) said: "Even so, ask permission." The man said: I serve her. He (peace and blessings be upon him) said: "Would you like to see her naked?" He said: No. He (peace and blessings be upon him) said: "Then ask permission."
