'Aisha (Allah be pleased with her) reported: One day Allah's Apostle (may peace be upon him) visited me looking pleased and he said: 'Aisha, don't you see Mujazziz al- Mudliji?(He) entered (my house) and saw Usama and Zaid with a rug over them covering their heads, but their feet appeared, and (he) said: These feet are related to one another.
