Sunan Abi Dawud Book 35, Hadith 55
When the Messenger of Allah (ﷺ) went on a journey, the last member of his family he saw was Fatimah, and the first he visited on his return was Fatimah. Once when he returned from an expedition she had hung up a hair-cloth, or a curtain, at her door, and adorned al-Hasan and al-Husayn with silver bracelets. So when he arrived, he did not enter. Thinking that he had been prevented from entering by what he had seen, she tore down the curtain, unfastened the bracelets from the boys and cut them off.
They went weeping to the Messenger of Allah (ﷺ), and when he had taken them from them, he said: Take this to so and so's family. Thawban. In Medina, these are my family, and I did not like them to enjoy their good things in the present life. Buy Fatimah a necklace or asb, Thawban, and two ivory bracelets.
The Prophet (ﷺ) said: At the end of time there will be people who will use this black dye like the crops of doves who will not experience the fragrance of Paradise.
The Messenger of Allah (ﷺ) wanted to write to some persian rulers. He was told that they would not read a letter without a seal in the form of a silver ring on which he engraved "Muhammad the Messenger of Allah."
