Some Zanadiqa (atheists) were brought to `Ali and he burnt them. The news of this event, reached Ibn
`Abbas who said, “If I had been in his place, I would not have burnt them, as Allah’s Messenger (ﷺ) forbade
it, saying, ‘Do not punish anybody with Allah’s punishment (fire).’ I would have killed them according
to the statement of Allah’s Messenger (ﷺ), ‘Whoever changed his Islamic religion, then kill him.’”
