Musnad Ahmad 769:25

Hushaym narrated to us, he said: Al-Shaybani informed me, he said: I said to Ibn Abi Awfa, "Did the Messenger of Allah (peace and blessings of Allah be upon him) stone [anyone]?" He said, "Yes, a Jew and a Jewess." He said: I said, "Was that after the revelation of [Surah] An-Nur or before it?" He said, "I do not know."
