Narrated Ash-Sharid ibn Suwayd ath-Thaqafi: Sharid's mother left a will to emancipate a believing slave on her behalf. So he came to the Prophet ﷺ and said: Messenger of Allah, my mother left a will that I should emancipate a believing slave for her, and I have a black Nubian slave-girl. He mentioned a tradition about the test of the girl. Abu Dawud said: Khalid bin Abdullah narrated this tradition direct from the Prophet ﷺ. He did not mention the name of al-Sharid.
