Abu Dawud Book 28, Hadith Number 4201.

Chapter : Use of ivory.

Narated By Thawban : When the Apostle of Allah (PBUH) 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 Apostle of Allah (PBUH), 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.
