'Alqama said, "A man came to 'Abdullah and said, 'Should I ask
permission to go in where my mother is?' He said, 'At all times. Do you
want to see her (exposed)?'"
Muslim ibn Nadhir said, "A man asked Hudhayfa, 'Should I ask permission
to enter where my mother is?' He replied, 'If you were not to ask her permission,
you would see what you dislike.'"
