Book of Knowledge

(7) Chapter: What is said regarding the hand to hand exchange (of books of knowledge), and the writing of knowledge by religious scholars to different countries

Hadith 65

Narrated Anas bin Malik:

Once the Prophet (صلى الله عليه وسلم) wrote a letter or had an idea of writing a letter. The Prophet (صلى الله عليه وسلم) was told that they (rulers) would not read letters unless they were sealed. So the Prophet (صلى الله عليه وسلم) got a silver ring made with "Muhammad Allah's Messenger (صلى الله عليه وسلم)" engraved on it. As if I were just observing its white glitter in the hand of the Prophet.
