Anas said that when the Prophet wanted to write to the Persian Emperor, the Byzantine Emperor and the Negus he was told that they would not accept a letter without a seal; so God’s messenger fashioned a seal in the form of a silver ring on which he engraved “Muhammad God’s messenger.”
Muslim transmitted it. A version by Bukhari says the engraving on the seal was in three lines, “Muhammad” being one, “messenger” another, and “of God” another.
‘Abdallah b. ‘Abbas told that when God’s messenger saw a gold signet-ring on a man’s hand he pulled it off and threw it away saying, “One of you is making for a coal from hell and putting it on his hand.” After God’s messenger had departed someone said to the man, “Take your signet-ring and get some good from it,” but he replied, “No, I swear by God that I shall never take it when God’s messenger has thrown it away.”
Muslim transmitted it.
‘Ali said God's messenger forbade wearing Qassi material and anything dyed with saffron, using a gold ring, and reciting the Qur'an when making the bow.
Muslim transmitted it.
