الطبراني:٢٠٢٦٦ – حَدَّثَنَا سَعِيدُ بْنُ عَبْدِ الرَّحْمَنِ التُّسْتَرِيُّ ثنا إِبْرَاهِيمُ بْنُ الْمُسْتَمِرِّ الْعُرُوقِيُّ ثنا أَبُو هَمَّامٍ الْخَارِكِيُّ حَدَّثَنِي عَدِيُّ بْنُ أَبِي عَدِيٍّ عَنْ عَلِيِّ بْنِ زَيْدٍ عَنِ الْحَسَنِ عَنْ أُمِّهِ عَنْ أُمِّ سَلَمَةَ

أَنَّ النَّبِيَّ ﷺ قَالَ «فِي كُلِّ رَكْعَةٍ تَشَهُّدٌ وَتَسْلِيمٌ عَلَى الْمُرْسَلِينَ وَعَلَى مَنْ تَبِعَهُمْ مِنْ عِبَادِ اللهِ الصَّالِحِينَ»
