(36) باب مَنْ جَلَسَ فِي الْمَسْجِدِ يَنْتَظِرُ الصَّلاَةَ، وَفَضْلِ الْمَسَاجِدِ
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."
