سنن النسائي

It was narrated from An-Nu'man bin Bashir that a man called 'Abdur-Rahman bin Hunain or Yunbaz Qurqur had intercourse with his wife's slave woman, and it was brought to An-Nu'man bin Bashir. He said: "I will pass the same judgment concerning her as the Messenger of Allah (ﷺ) did. If she let you do that, I will flog you, but if she did not let you do that, I will stone you (to death)." She had let him do that so he flogged him with one hundred stripes. (One of the narrators) Qatadah said: "I wrote to Habib bin Salim and he wrote back to me with this information."
