Narrated 'Ikrimah: That 'Ali burnt some people who apostasized from Islam. This news reached Ibn 'Abbas, so he said: "If it were me I would have killed them according to the statement of Messenger of Allah (ﷺ). The Messenger of Allah (ﷺ) said: “Whoever changes his religion then kill him.' And I would not have burned them because the Messenger of Allah (ﷺ) said: “Do not punish with the punishment of Allah.' So this reached 'Ali, and he said: "Ibn 'Abbas has told the truth””
