It is narrated from Sayyida Aisha (may Allah be pleased with her) that Sayyiduna Usama bin Zaid (may Allah be pleased with him) fell on the door frame and got a wound on his forehead. (And in another narration, it is mentioned that blood started to flow.) So the Messenger of Allah (peace and blessings be upon him) said to me: Clean the blood from his forehead. But I felt some aversion, so the Messenger of Allah (peace and blessings be upon him) himself started to suck the wound and kept spitting it out, and he (peace and blessings be upon him) said: If Usama (may Allah be pleased with him) were a girl, I would have dressed him in fine clothes and jewelry and made him so beautiful that people would desire to marry him.
