أَخْبَرَنِي مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ عَمَّارٍ الْمَوْصِلِيُّ، عَنِ الْمُعَافَى، عَنْ عِصَامِ بْنِ قُدَامَةَ، عَنْ مَالِكٍ، - وَهُوَ ابْنُ نُمَيْرٍ الْخُزَاعِيِّ - عَنْ أَبِيهِ، قَالَ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم وَاضِعًا يَدَهُ الْيُمْنَى عَلَى فَخِذِهِ الْيُمْنَى فِي الصَّلاَةِ وَيُشِيرُ بِأُصْبُعِهِ ‏.‏
