It was narrated that 'Aishah, may Allah be pleased with her, said: "The Messenger of Allah came to me one day looking happy and said: 'O 'Aishah! Did you not see that Mujazziz Al-Mudliji came to me when Usamah bin Zaid was with me. He saw Usamah bin Zaid and Zaid with a blanket over them; their heads were covered but their feet were exposed, and he said: These feet belong to one another.'"
أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، رضى الله عنها قَالَتْ دَخَلَ عَلَىَّ رَسُولُ اللَّهِ صلى الله عليه وسلم ذَاتَ يَوْمٍ مَسْرُورًا فَقَالَ " يَا عَائِشَةُ أَلَمْ تَرَىْ أَنَّ مُجَزِّزًا الْمُدْلِجِيَّ دَخَلَ عَلَىَّ وَعِنْدِي أُسَامَةُ بْنُ زَيْدٍ فَرَأَى أُسَامَةَ بْنَ زَيْدٍ وَزَيْدًا وَعَلَيْهِمَا قَطِيفَةٌ وَقَدْ غَطَّيَا رُءُوسَهُمَا وَبَدَتْ أَقْدَامُهُمَا فَقَالَ هَذِهِ أَقْدَامٌ بَعْضُهَا مِنْ بَعْضٍ " .
