Hanad bin al-Sari bin Mus'ab هناد بن السري بن مصعب · The Book of Adornment

"The Messenger of Allah wanted to write to the Romans, and they (the Companions) said: 'They do not read any letter unless it has a seal.' So he took a ring of silver and it is as if I can see its whiteness on his hand, and engraved on it (were the words): 'Muhammad Rasul Allah.'"

"The Messenger of Allah came from a journey, and I had hung a curtain on which there were images over a niche. He took it down and said: 'The people who will be most severely punished on the Day of Resurrection will be those who try to match the creation of Allah.'"
