Did Hadrat Muhammad (SAW) have a slave or not?

It was narrated from Anas, that the Messenger of Allah had a female slave with whom he had intercourse, but 'Aishah and Hafsah would not leave him alone until he said that she was forbidden for him. Then Allah, the Mighty and Sublime, revealed: "O Prophet! Why do you forbid (for yourself) that which Allah has allowed to you.' until the end of the Verse. https://sunnah.com/nasai:3959 Narrated 'Amir bin Al-Harith: Allah's Messenger (ﷺ) did not leave a Dinar or a Dirham or a male or a female slave. He left only his white mule on which he used to ride, and his weapons, and a piece of land which he gave in charity for the needy travelers. https://sunnah.com/bukhari:4461 Are these contradictions? Cause first says that there was a female slave and second says there was no male or female slave.
