Musannaf Ibn Abi Shayba 19:853

Abu Bakr narrated to us, he said: Muhammad ibn Bakr narrated to us, from Ibn Jurayj, he said: Ma’mar informed me, from Ibn Shihab, that a man struck a man with a sword, and Marwan ibn al-Hakam did not cut off his hand. And Umar ibn Abd al-Aziz cut off the hand of a man for that, by a letter from al-Walid ibn Abd al-Malik.
