حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَابْنُ، نُمَيْرٍ قَالاَ حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنْ عَاصِمٍ، عَنْ عَبْدِ اللَّهِ بْنِ الْحَارِثِ، عَنْ عَائِشَةَ، قَالَتْ كَانَ النَّبِيُّ صلى الله عليه وسلم إِذَا سَلَّمَ لَمْ يَقْعُدْ إِلاَّ مِقْدَارَ مَا يَقُولُ " اللَّهُمَّ أَنْتَ السَّلاَمُ وَمِنْكَ السَّلاَمُ تَبَارَكْتَ ذَا الْجَلاَلِ وَالإِكْرَامِ " . وَفِي رِوَايَةِ ابْنِ نُمَيْرٍ " يَا ذَا الْجَلاَلِ وَالإِكْرَامِ " .
'A'isha reported: When the Messenger of Allah (ﷺ) pronounced salutation, he salutation longer than it took him to say: O Allah: You are Peace, and peace comes from You, blessed are You, Possessor of Glory and ]Honour; and in the narration of Ibn Numair the words are:" O Possessor of Glory and Honour."
