(108) باب مَا يَقُولُ إِذَا سَلَّمَ مِنَ الصَّلاَةِ
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.'"
