Chapter: The Prophet (SAW) Acquired A Ring When He Wanted To Send Letters To The Non-Arabs
Anas b. Malik reported that when Allah's Messenger ( صلی اللہ علیہ وسلم ) decided to write letters to the Byzantine (Emperor) they (his Companions) told him that they would not read a letter unless it is sealed. (Then) Allah's Messenger ( صلی اللہ علیہ وسلم ) had a silver ring made (for himself), (its shape is so vivid in my mind) as if I see its brightness in the band of Allah's Messenger ( صلی اللہ علیہ وسلم ) and its engravement was (Muhammad, Messenger of Allah).
Anas reported that when Allah's Apostle ( صلی اللہ علیہ وسلم ) decided to write (letters) to non-Arabs (i. e. Persian and Byzantine Emperors) it was said to him that the non-Arabs would not accept a letter but that having a seal over it; so he (the Holy Prophet) got a silver ring made. He (Anas) said: I perceive as if I am looking at its brightness in his hand.
Anas reported that when Allah's Apostle ( صلی اللہ علیہ وسلم ) decided to write to the Kisra (the King of Persia), Caesar (Emperor of Rome), and the Negus (the Emperor of Abyssinia), it was said to him that they would not accept the letter without the seal over it; so Allah's Messenger ( صلی اللہ علیہ وسلم ) got a seal made, the ring of which was made of silver and there was engraved on it: Muhammad, the Messenger of Allah.
