She said: One day God's Messenger visited me looking pleased and asked if I was not surprised to hear that Mujazziz al-Mudlijl[1] had entered, and seeing Usama and Zaid[2] with a rug over them covering their heads and letting their feet appear, said, “These feet are related.” (Bukhari and Muslim.) 1.
