Musannaf Ibn Abi Shaybah 35355 — Those who forbade burning with fire

Ikrimah (may Allah have mercy on him) said that Sayyiduna Ibn Abbas (may Allah be pleased with them both) mentioned the people whom Sayyiduna Ali (may Allah be pleased with him) had burned, and then said: If it had been me, I would never have burned those people in fire, because of the saying of the Messenger of Allah (peace and blessings be upon him): "Do not punish in the manner of Allah's punishment." And if it had been me, I would have killed them, because of the noble saying of the Messenger of Allah (peace and blessings be upon him): "Whoever changes his religion, kill him."
