It was narrated that 'Aishah said: “The Messenger of Allah (ﷺ) came in one day looking happy, and said: 'O 'Aishah, did you not see that Mujazziz Al-Mudliji entered upon me and saw Usamah and Zaid. There was a blanket over them and their faces were covered but their feet were exposed, and he said: 'These feet belong to one another'.”
