Musannaf Ibn Abi Shaybah 25174 — The dislike of cauterization

Muhammad bin Amr narrates from his father, from his grandfather, who said: I was afflicted with pleurisy (dhat al-janb) in the time of Sayyiduna Umar (may Allah be pleased with him). A bedouin was called to cauterize me, but he refused to do so without the permission of Sayyiduna Umar. So my father went to Sayyiduna Umar and told him what had happened, and Sayyiduna Umar said: "You must not go near the fire, for this patient has an appointed time which he can neither go beyond nor fall short of."
