"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."
سُئِلَ أَنَسٌ هَلِ اتَّخَذَ النَّبِيُّ ﷺ خَاتَمًا قَالَ نَعَمْ أَخَّرَ لَيْلَةً صَلاَةَ الْعِشَاءِ الآخِرَةِ إِلَى قَرِيبٍ مِنْ شَطْرِ اللَّيْلِ فَلَمَّا أَنْ صَلَّى أَقْبَلَ النَّبِيُّ ﷺ عَلَيْنَا بِوَجْهِهِ ثُمَّ قَالَ إِنَّكُمْ لَنْ تَزَالُوا فِي صَلاَةٍ مَا انْتَظَرْتُمُوهَا قَالَ أَنَسٌ كَأَنِّي أَنْظُرُ إِلَى وَبِيصِ خَاتَمِهِ فِي حَدِيثِ عَلِيٍّ إِلَى شَطْرِ اللَّيْلِ
