عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا قَالَ: كُنْتُ أَعْرِفُ انْقِضَاءَ صَلَاةِ رَسُولِ اللَّهِ صَلَّى الله عَلَيْهِ وَسلم بِالتَّكْبِيرِ

‘A’isha said that when God’s Messenger uttered the salutation he sat no longer than it took to say, “O God, Thou art Peace, and peace comes from Thee. Blessed art Thou, O Possessor of glory and honour.” Muslim transmitted it.
