حَدَّثَنَا إِسْحَقُ بْنُ مَنْصُورٍ أَخْبَرَنَا مُعَاذُ بْنُ هِشَامٍ حَدَّثَنِي أَبِي عَنْ قَتَادَةَ عَنْ أَنَسِ بْنِ مَالِکٍ قَالَ لَمَّا أَرَادَ نَبِيُّ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ أَنْ يَکْتُبَ إِلَی الْعَجَمِ قِيلَ لَهُ إِنَّ الْعَجَمَ لَا يَقْبَلُونَ إِلَّا کِتَابًا عَلَيْهِ خَاتَمٌ فَاصْطَنَعَ خَاتَمًا قَالَ فَکَأَنِّي أَنْظُرُ إِلَی بَيَاضِهِ فِي کَفِّهِ قَالَ أَبُو عِيسَی هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ
جامع ترمذی · Hadith 2718
Narrated Anas bin Malik: When the Prophet of Allah (ﷺ) wanted to write to the foreigners, it was said to him: 'The foreigners do not accept a letter unless it has a seal.' So he had a ring made. He said: It is as if I am now looking at its whiteness in his hand.
