When the Messenger of Allah ﷺ pronounced salutation, he salutation longer than it took him to say: O Allah: Thou art Peace, and peace comes from Thee, blessed art Thou, Possessor of Glory and ]Honour; and in the narration of Ibn Numair the words are:" O Possessor of Glory and Honour."
كَانَ النَّبِيُّ ﷺ 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
