صَلَّيْتُ مَعَ عَلِيٍّ وَعَبْدِ اللهِ فَرَأَيْتُهُمَا يُسَلِّمَانِ عَنْ أَيْمَانِهِمَا وَعَنْ شَمَائِلِهِمَا السَّلَامُ عَلَيْكُمْ وَرَحْمَةُ اللهِ السَّلَامُ عَلَيْكُمْ وَرَحْمَةُ اللهِ وَزَعَمَ أَنَّهُمَا صَلَّيَا خَلْفَ رَسُولِ اللهِ ﷺ فَسَلَّمَ عَنْ يَمِينِهِ «السَّلَامُ عَلَيْكُمْ وَرَحْمَةُ اللهِ» وَعَنْ يَسَارِهِ «السَّلَامُ عَلَيْكُمْ وَرَحْمَةُ اللهِ» حَتَّى يُرَى بَيَاضُ خَدِّهِ مِنَ الْجَانِبَيْنِ
