Sunan an-Nasa'i, Book 48, Hadith 163 (In-Book) ⓘ

It was narrated that Anas said: "The Messenger of Allah [SAW] delayed 'Isha' prayer one night, until half the night had passed, then he came out and led us in prayer. And it is as if I can see the whiteness of his silver ring on his hand."

أَخْبَرَنَا أَحْمَدُ بْنُ عُثْمَانَ أَبُو الْجَوْزَاءِ، قَالَ حَدَّثَنَا أَبُو دَاوُدَ، قَالَ حَدَّثَنَا قُرَّةُ بْنُ خَالِدٍ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، قَالَ أَخَّرَ رَسُولُ اللَّهِ صلى الله عليه وسلم صَلاَةَ الْعِشَاءِ الآخِرَةِ حَتَّى مَضَى شَطْرُ اللَّيْلِ ثُمَّ خَرَجَ فَصَلَّى بِنَا كَأَنِّي أَنْظُرُ إِلَى بَيَاضِ خَاتَمِهِ فِي يَدِهِ مِنْ فِضَّةٍ ‏.‏
