Abu Basir al-Tartusi is the assumed name of Abd-al Mun'em Mustafa Halima (Arabic: عبد المنعم مصطفى حليمة), a Syrian cleric and jihadist theoretician.
"[1] Abu Basir was born in the Syrian city of Tartus, but was forced to flee Syria during the 1979–82 Islamist uprising against Hafez al-Assad and emigrated to London.
Two days after the bombing he published a fatwa on his website that protested the killing of British civilians as a “disgraceful and shameful act, with no manhood, bravery, or morality.
We cannot approve it nor accept it, and it is denied islamically and politically.” Abu Basir’s fatwa drew angry responses in Jihadi forums, which led him to publish another online declaration, “The Love of Revenge or the Legal Ruling,” on 11 July 2005.
[2] This appeared to be confirmed in an online video in October 2012, apparently filmed near Latakia where he is seen alongside scores of armed rebels in a paramilitary group called Ansar al-Sham.
