حَدَّثَنَا أَحْمَدُ بْنُ مَنِيعٍ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنْ عَاصِمٍ الأَحْوَلِ، عَنْ عَبْدِ اللَّهِ بْنِ الْحَارِثِ، عَنْ عَائِشَةَ، قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا سَلَّمَ لاَ يَقْعُدُ إِلاَّ مِقْدَارَ مَا يَقُولُ " اللَّهُمَّ أَنْتَ السَّلاَمُ وَمِنْكَ السَّلاَمُ تَبَارَكْتَ ذَا الْجَلاَلِ وَالإِكْرَامِ " .
Aishah narrated: "When Allah's Messenger said the Salam he would not remain seated except long enough to say: (Allahumma antas-salam, wa minkas-salam, tabarakta dhal jalali wal-Ikram) 'O Allah! You are the One free of defects, and perfection is from You. Blessed are You, Possessor of Majesty and Honor.'" Translation Not Available
