Humaid said:"Anas was asked: 'Did the Prophet (ﷺ) use a ring?' He said: 'Yes. One night he delayed the later 'Isha' prayer, until almost halfway through the night. When he prayed the Prophet (ﷺ) turned his face toward us and said: 'You are still in a state of prayer so long as you waiting for it.'" Anas said: 'It is as if I can see the luster of his ring.' According to the narration of 'Ali - that is, Ibn Hujr - "until halfway through the night."
أَخْبَرَنَا عَلِيُّ بْنُ حُجْرٍ، قَالَ حَدَّثَنَا إِسْمَاعِيلُ، ح وَأَنْبَأَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ حَدَّثَنَا خَالِدٌ، قَالاَ حَدَّثَنَا حُمَيْدٌ، قَالَ سُئِلَ أَنَسٌ هَلِ اتَّخَذَ النَّبِيُّ صلى الله عليه وسلم خَاتَمًا قَالَ نَعَمْ أَخَّرَ لَيْلَةً صَلاَةَ الْعِشَاءِ الآخِرَةِ إِلَى قَرِيبٍ مِنْ شَطْرِ اللَّيْلِ فَلَمَّا أَنْ صَلَّى أَقْبَلَ النَّبِيُّ صلى الله عليه وسلم عَلَيْنَا بِوَجْهِهِ ثُمَّ قَالَ " إِنَّكُمْ لَنْ تَزَالُوا فِي صَلاَةٍ مَا انْتَظَرْتُمُوهَا " . قَالَ أَنَسٌ كَأَنِّي أَنْظُرُ إِلَى وَبِيصِ خَاتَمِهِ . فِي حَدِيثِ عَلِيٍّ إِلَى شَطْرِ اللَّيْلِ .
