The Prophet ﷺ delayed the ʿIsha' prayer till midnight and then he offered the prayer and said, "The people prayed and slept but you have been in prayer as long as you have been waiting for it (the prayer)." Anas added: As if I am looking now at the glitter of the ring of the Prophet ﷺ on that night.  

أَخَّرَ النَّبِيُّ ﷺ صَلاَةَ الْعِشَاءِ إِلَى نِصْفِ اللَّيْلِ ثُمَّ صَلَّى ثُمَّ قَالَ قَدْ صَلَّى النَّاسُ وَنَامُوا أَمَا إِنَّكُمْ فِي صَلاَةٍ مَا انْتَظَرْتُمُوهَا وَزَادَ ابْنُ أَبِي مَرْيَمَ أَخْبَرَنَا يَحْيَى بْنُ أَيُّوبَ حَدَّثَنِي حُمَيْدٌ سَمِعَ أَنَسًا كَأَنِّي أَنْظُرُ إِلَى وَبِيصِ خَاتَمِهِ لَيْلَتَئِذٍ
