Musannaf Ibn Abi Shayba 19:99

Abu Bakr narrated to us, he said: Sahl ibn Yusuf narrated to us, from ‘Amr, from al-Hasan, regarding the man who is apprehended having committed adultery more than once with a single woman, or with more than that of women: He said, "Upon him is one prescribed punishment (hadd)." And the thief who is apprehended having stolen repeatedly, it is the same as that.
