Then he came, facing us ..... as if l am now Looking at the glitter of his ring ..... and said, "The people have offered their prayers and slept but you have been in prayer as you have been waiting for it."

حَدَّثَنَا عَبْدَانُ، أَخْبَرَنَا يَزِيدُ بْنُ زُرَيْعٍ، أَخْبَرَنَا حُمَيْدٌ، قَالَ سُئِلَ أَنَسٌ هَلِ اتَّخَذَ النَّبِيُّ صلى الله عليه وسلم خَاتَمًا قَالَ أَخَّرَ لَيْلَةً صَلاَةَ الْعِشَاءِ إِلَى شَطْرِ اللَّيْلِ، ثُمَّ أَقْبَلَ عَلَيْنَا بِوَجْهِهِ، فَكَأَنِّي أَنْظُرُ إِلَى وَبِيصِ خَاتَمِهِ‏.‏ قَالَ ‏ "‏ إِنَّ النَّاسَ قَدْ صَلَّوْا وَنَامُوا، وَإِنَّكُمْ لَمْ تَزَالُوا فِي صَلاَةٍ مَا انْتَظَرْتُمُوهَا ‏"‏‏.‏
