حَدَّثَنَا مَالِكُ بْنُ إِسْمَاعِيلَ، قَالَ: حَدَّثَنَا ابْنُ عُيَيْنَةَ قَالَ: سَمِعْتُ الزُّهْرِيَّ يُحَدِّثُهُ، عَنْ عَبَّادِ بْنِ تَمِيمٍ، عَنْ عَمِّهِ
قَالَ: رَأَيْتُهُ، قُلْتُ لِابْنِ عُيَيْنَةَ: النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ؟ قَالَ: نَعَمْ مُسْتَلْقِيًا، وَاضِعًا إِحْدَى رِجْلَيْهِ عَلَى الأُخْرَى
Abdullah ibn Zayd ibn Asim al-Mazini said, “I saw him.” Malik ibn Ismail asked Ibn ‘Uyayna (who had transmitted this to him), ‘The Prophet (sallallahu alayhi wa sallam), may Allah bless him and grant him peace?’ He replied, ‘Yes, lying down with one of his feet over the other.’’
