Sunan Ibn Majah, Hadith 3640 ⓘ
It was narrated that Anas bin Malik said: “The Messenger of Allah had a ring made for him, and he said: ‘I have had a ring made for me and had it engraved, and no one should make a ring with similar engraving.’”
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا إِسْمَاعِيلُ ابْنُ عُلَيَّةَ، عَنْ عَبْدِ الْعَزِيزِ بْنِ صُهَيْبٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ اصْطَنَعَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ خَاتَمًا فَقَالَ " إِنَّا قَدِ اصْطَنَعْنَا خَاتَمًا وَنَقَشْنَا فِيهِ نَقْشًا فَلاَ يَنْقُشَنَّ عَلَيْهِ أَحَدٌ " .
