In response to a question posted on his Ask.fm page, which asked about ISIS Spokesman Abu Mohammad al-Adnani’s advocating of the killing of civilians:

“Killing men from the kuffar [disbelievers] is halal [permissible]. I don’t think it’s the wisest choice. Uthaymeen released a fatwa saying killing children of kuffar through qisas is halal [forbidden]. I disagree with that as well. Killing the men without a treaty is halal, this is well known from the Sunnah [tradition of the Prophet].” (Tweet)“Teen IS supporter in Virginia was a staple of IS online community,” Insite Blog on Terrorism & Extremism, June 12, 2015, http://news.siteintelgroup.com/blog/index.php/entry/386-teen-is-supporter-in-virginia-was-a-staple-of-is-online-community.
