What Has Been Related About Putting A Seal On A Letter

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."

حَدَّثَنَا إِسْحَاقُ بْنُ مَنْصُورٍ، أَخْبَرَنَا مُعَاذُ بْنُ هِشَامٍ، حَدَّثَنِي أَبِي، عَنْ قَتَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ لَمَّا أَرَادَ نَبِيُّ اللَّهِ ﷺ أَنْ يَكْتُبَ إِلَى الْعَجَمِ قِيلَ لَهُ إِنَّ الْعَجَمَ لاَ يَقْبَلُونَ إِلاَّ كِتَابًا عَلَيْهِ خَاتَمٌ فَاصْطَنَعَ خَاتَمًا . قَالَ فَكَأَنِّي أَنْظُرُ إِلَى بَيَاضِهِ فِي كَفِّهِ .

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
