عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: مَا كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَجْلِسُ بَعْدَ صَلَاتِهِ إِلَّا قَدْرَ مَا يَقُولُ: ((اللَّهُمَّ أَنْتَ السَّلَامُ وَمِنْكَ السَّلَامُ تَبَارَكْتَ يَا ذَا الْجَلَالِ وَالْإِكْرَامِ))
Sayyidah Aisha (may Allah be pleased with her) says: The Noble Prophet (peace and blessings be upon him) used to remain after his prayer for as long as it took to recite this supplication: "O Allah! You are As-Salam and from You is peace. Blessed are You, O Possessor of Majesty and Honor." (O Allah! You are As-Salam and peace is from You. O Possessor of Majesty and Honor, You are greatly blessed.)
