Musannaf Ibn Abi Shaybah 30159 — A man whose slave commits zina

The father of Ash'ath said: I was present with Sayyiduna Abu Barzah (may Allah be pleased with him). He beat a slave woman of his who had done a sinful act. The narrator said: That slave woman had a sheet wrapped around her, and with him was a group of people. He recited this verse, the translation of which is: "And let a group of the believers witness their punishment." [Surah An-Nur: 2]
