Sahih Muslim Book - 37, Hadith - 5477

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ وَعَمْرٌو النَّاقِدُ وَمُحَمَّدُ بْنُ عَبَّادٍ وَابْنُ أَبِي عُمَرَ وَاللَّفْظُ لِأَبِي بَكْرٍ قَالُوا: حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ عَنْ أَيُّوبَ بْنِ مُوسَى عَنْ نَافِعٍ عَنْ ابْنِ عُمَرَ قَالَ:اتَّخَذَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خَاتَمًا مِنْ ذَهَبٍ ثُمَّ أَلْقَاهُ ثُمَّ اتَّخَذَ خَاتَمًا مِنْ وَرِقٍ وَنَقَشَ فِيهِ مُحَمَّدٌ رَسُولُ اللَّهِ وَقَالَ: لَا يَنْقُشْ أَحَدٌ عَلَى نَقْشِ خَاتَمِي هَذَا وَكَانَ إِذَا لَبِسَهُ جَعَلَ فَصَّهُ مِمَّا يَلِي بَطْنَ كَفِّهِ وَهُوَ الَّذِي سَقَطَ مِنْ مُعَيْقِيبٍ فِي بِئْرِ أَرِيسٍ.

It was narrated that Ibn 'Umar said: "The Prophet (s.a.w) acquired a ring of gold, then he threw it away and acquired a ring of silver, on which was engraved 'Muhammad Rasul Allah.' And he said: 'No one should have an engraving like this engraving of mine.' When he wore it, he put the stone towards his palm, and this is the ring that fell from the hand of Mu'aiqib into the well of Aris."
