Jabir bin Abdullah reported,

A man from the Ansar declared that his slave would be freed upon his death, and he had no other property besides him. News of this reached the Messenger of Allah ﷺ, who said, "Who will buy him from me?"Naeem bin Naham bought him for eight hundred dirhams.The narrator said, I heard Jabir say he was a Coptic slave who died in the first year.
