حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ الْأَنْصَارِيُّ قَالَ حَدَّثَنِي أَبِي عَنْ ثُمَامَةَ عَنْ أَنَسٍ أَنَّ أَبَا بَکْرٍ رَضِيَ اللَّهُ عَنْهُ لَمَّا اسْتُخْلِفَ بَعَثَهُ إِلَی الْبَحْرَيْنِ وَکَتَبَ لَهُ هَذَا الْکِتَابَ وَخَتَمَهُ بِخَاتَمِ النَّبِيِّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ وَکَانَ نَقْشُ الْخَاتَمِ ثَلَاثَةَ أَسْطُرٍ مُحَمَّدٌ سَطْرٌ وَرَسُولُ سَطْرٌ وَاللَّهِ سَطْرٌ
صحیح بخاری · Hadith 3106
Narrated Anas: That when Abu Bakr became the Caliph, he sent him to Bahrain and wrote this letter for him, and stamped it with the Ring of the Prophet. Three lines were engraved on the Ring, (the word) 'Muhammad' was in a line, 'Apostle' was in another line, and 'Allah' in a third.
