Narrated `Aisha: Once Allah's Messenger (ﷺ) entered upon me and he was in a very happy mood and said, "O `Aisha: Don't you know that Mujazziz Al-Mudliji entered and saw Usama and Zaid with a velvet covering on them and their heads were covered while their feet were uncovered. He said, 'These feet belong to each other.'

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، قَالَتْ دَخَلَ عَلَىَّ رَسُولُ اللَّهِ صلى الله عليه وسلم ذَاتَ يَوْمٍ وَهْوَ مَسْرُورٌ فَقَالَ " يَا عَائِشَةُ أَلَمْ تَرَىْ أَنَّ مُجَزِّزًا الْمُدْلِجِيَّ دَخَلَ فَرَأَى أُسَامَةَ وَزَيْدًا وَعَلَيْهِمَا قَطِيفَةٌ، قَدْ غَطَّيَا رُءُوسَهُمَا وَبَدَتْ أَقْدَامُهُمَا، فَقَالَ إِنَّ هَذِهِ الأَقْدَامَ بَعْضُهَا مِنْ بَعْضٍ ".
