"The Messenger of Allah ﷺ had a ring made from silver, so he had 'Muhammad, the Messenger of Allah' engraved on it. Then he said: 'Do not engrave with it.' (Using translation from Tirmidhī 1745)
أَنَّ النَّبِيَّ ﷺ صَنَعَ خَاتَمًا مِنْ وَرِقٍ فَنَقَشَ فِيهِ مُحَمَّدٌ رَسُولُ اللهِ ﷺ وَقَالَ لَا تَنْقُشُوا عَلَيْهِ
