What did `Umar report when he entered the Prophets (saw) attic room and saw the black slave at the top of the stairs?
 Narrated `Umar:                     I came and behold, Allah's Apostle was staying on a Mashroba (attic room) and a black slave of Allah's Apostle was at the top if its stairs. I said to him, "(Tell the Prophet) that here is `Umar bin Al- Khattab (asking for permission to enter)." Then he admitted me.
