From an interview of Al-Jazeera TV with [ Abu Hafs Al-Mauritani ], former Mufti for Al-Qaeda, who belonged to the organization's leadership from the early 1990s until 2001. He tells that he early expressed his opposition to Osama Bin Laden's ideology regarding the targeting of innocent civilians in the frame of planned operations in Western countries and which finally led to his separation from Al-Qaeda organization. He now lives in Mauritania.
Here Al-Mauritani's stance:
" When Al-Qaeda insisted on doing the 9/11 attacks, I was completely against that. ..... I say what ISIL or Al-Qaeda did in terms of killing innocent civilians is condemned by Islamic law, is morally condemnable and is not even politically expedient in terms of how it impacts our causes. Similarly we condemn all the evil which Western countries commit against Muslims ..... "
