English translation
[5480] 56 - (...) It was narrated that Anas bin Mâlik said: "When the Messenger of Allāh ﷺ wanted to send a letter to the Byzantines, they (the people) said: 'They do not read any letter unless it is sealed.' So the Messenger of Allāh ﷺ acquired a ring of silver. It is as if I can see its brightness on the hand of the Messenger of Allāh ﷺ, and its inscription said: 'Muḥammad Rasûl Allāh.'
