Musannaf Ibn Abi Shaybah 28931 — The spine: how much is due for it?

Muhammad bin Abdullah said: I was present with Sayyiduna Ibn al-Zubayr (may Allah be pleased with him) in the case of a man whose back had been broken, so that he became hunchbacked. He was not left sitting, but walked hunched over. Ibn al-Zubayr said to him: Walk. So he walked, and Ibn al-Zubayr ruled two-thirds of the blood money (diyah) for him.
