البيهقي:٣٤٣٠أَخْبَرَنَا عَلِيُّ بْنُ مُحَمَّدِ بْنِ عَبْدِ اللهِ بْنِ بِشْرَانَ أنبأ أَبُو مُحَمَّدٍ دَعْلَجُ بْنُ أَحْمَدَ ثنا إِبْرَاهِيمُ بْنُ عَلِيٍّ ثنا يَحْيَى بْنُ يَحْيَى أنبأ هُشَيْمٌ عَنْ حُصَيْنٍ عَنْ عَبْدِ الْمَلِكِ عَنْ عَمْرِو بْنِ حُرَيْثٍ قَالَ

كَانَ رَسُولُ اللهِ ﷺ يَضَعُ الْيُمْنَى عَلَى الْيُسْرَى فِي الصَّلَاةِ وَرُبَّمَا مَسَّ لِحْيَتَهُ وَهُوَ يُصَلِّي هَكَذَا  

رَوَاهُ هُشَيْمُ بْنُ بَشِيرٍ وَرَوَاهُ شُعْبَةُ
