The Prophet ﷺ, after giving the closing salutation of the prayer, would not remain seated longer than it took to say, "O Allah, You are Peace, and from You comes peace. Blessed are You, Possessor of Majesty and Honor."In the version reported by Ibn Numayr, the wording is, "O Possessor of Majesty and Honor."
كان النبي ﷺ إذا سلم لم يقعد إلا مقدار ما يقول: اللهم أنت السلام، ومنك السلام، تباركت ذا الجلال والإكرام وفي رواية ابن نمير: يا ذا الجلال والإكرام.
