Sahih Muslim 640bBook 5, Hadith 282
وَحَدَّثَنِي حَجَّاجُ بْنُ الشَّاعِرِ، حَدَّثَنَا أَبُو زَيْدٍ، سَعِيدُ بْنُ الرَّبِيعِ حَدَّثَنَا قُرَّةُ بْنُ خَالِدٍ، عَنْ قَتَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ نَظَرْنَا رَسُولَ اللَّهِ صلى الله عليه وسلم لَيْلَةً حَتَّى كَانَ قَرِيبٌ مِنْ نِصْفِ اللَّيْلِ ثُمَّ جَاءَ فَصَلَّى ثُمَّ أَقْبَلَ عَلَيْنَا بِوَجْهِهِ فَكَأَنَّمَا أَنْظُرُ إِلَى وَبِيصِ خَاتَمِهِ فِي يَدِهِ مِنْ فِضَّةٍ .
We waited for the Messenger of Allah (may peace be upon hi n) one night, till it was about midnight. He (the Holy Prophet) came and observed prayer and then turned his face towards us, as it I was seeing the lustre of the silver ring on his finger.
