Musannaf Ibn Abi Shaybah 35365 — Those who permitted burning in enemy

Abd al-Rahman bin Ubayd (may Allah have mercy on him) said that his father Ubayd (may Allah have mercy on him) said: There were some people who used to take stipends and salaries and pray with the people, and in secret they would worship idols. These people were brought to Sayyiduna Ali bin Abi Talib (may Allah be pleased with him), and he (may Allah be pleased with him) confined them in the mosque or in the prison. Then he said: O people, what is your view concerning those who take stipends and salaries along with you and worship these idols? The people said: Kill them. He (may Allah be pleased with him) said: No. Rather, I will deal with them as they dealt with our forefather Ibrahim (peace be upon him). So he (may Allah be pleased with him) burned them in fire.
