In the article “Kill the Imam of Kufr in the West,” Dabiq Issue 14:
“It should then be no surprise that [Abu Bakr al-Baghdadi] declared that any of the apostates from the sahwāt or otherwise who repent to Allah and surrender themselves to the Islamic State will be guaranteed amnesty, even if they had killed a million mujāhidīn. But those who are caught before they repent, then there is no amnesty for them and theirs shall be a painful – and fatal – punishment.”“Kill the Imams of Kufr in the West,” Dabiq, April 2016, 9, https://azelin.files.wordpress.com/2016/04/the-islamic-state-22dacc84biq-magazine-1422.pdf; Graeme Wood, “The American Climbing the Ranks of ISIS,” Atlantic, updated January 25, 2017, https://www.theatlantic.com/magazine/archive/2017/03/the-american-leader-in-the-islamic-state/510872/.
