باب مَنْ جَلَسَ فِي الْمَسْجِدِ يَنْتَظِرُ الصَّلاَةَ، وَفَضْلِ الْمَسَاجِدِ
Sahih al-Bukhari 661

Narrated Humaid:

Anas was asked, "Did Allah's Messenger (ﷺ) wear a ring?" He said, "Yes. Once he delayed the `Isha' prayer till midnight 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 صلى الله عليه وسلم 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.‏
