Narrated Humaid:

Anas was asked, "Did Allah's Apostle wear a ring?" He said, "Yes. Once he delayed the 'Isha' prayer till mid-night and after the prayer, he faced us and said, 'The people prayed and have slept and you remained in prayer as long as you waited for it.' " Anas added, "As if I were just now observing the glitter of his ring."

حَدَّثَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا إِسْمَاعِيلُ بْنُ جَعْفَرٍ، عَنْ حُمَيْدٍ، قَالَ سُئِلَ أَنَسٌ هَلِ اتَّخَذَ رَسُولُ اللَّهِ ﷺ خَاتَمًا فَقَالَ نَعَمْ، أَخَّرَ لَيْلَةً صَلاَةَ الْعِشَاءِ إِلَى شَطْرِ اللَّيْلِ، ثُمَّ أَقْبَلَ عَلَيْنَا بِوَجْهِهِ بَعْدَ مَا صَلَّى فَقَالَ
" صَلَّى النَّاسُ وَرَقَدُوا وَلَمْ تَزَالُوا فِي صَلاَةٍ مُنْذُ انْتَظَرْتُمُوهَا ". قَالَ فَكَأَنِّي أَنْظُرُ إِلَى وَبِيصِ خَاتَمِهِ.
