Musannaf Ibn Abi Shaybah 35354 — Those who forbade burning with fire

Sayyiduna Abu Hurayrah al-Dawsi (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) sent us out in a force and said: "If you gain victory over so-and-so and so-and-so, burn those two men." Then, when the next day came, he (peace and blessings be upon him) sent a messenger to us, saying: "I had ordered you to burn these two men, and my view now is that it is not fitting for anyone besides Allah to punish with fire. So if you gain victory over the two of them, kill them."
