Hadith text
Narrated Anas bin Malik:Once the Prophet (ﷺ) wrote a letter or had an idea of writing a letter. The Prophet (ﷺ) was told that they (rulers) would not read letters unless they were sealed. So the Prophet (ﷺ) got a silver ring made with "Muhammad Allah's Messenger (ﷺ)" engraved on it. As if I were just observing its white glitter in the hand of the Prophet
Anas bin Malik (رضی اللہ عنہ) se riwayat hai ke Nabi (ﷺ) ne ek khat likha ya likhne ka iraada kiya. Aap ko bataya gaya ke woh (badshah) mohar-band khat hi parhte hain. To Nabi ne chandi ki ek angoothi banwai jis par "Muhammad Rasoolallah" likha hua tha — goya main abhi tak uski safed chamak Nabi (ﷺ) ke haath mein dekh raha hoon.
