Moroccans are largely Maliki. ISIS is Hanbali. More specifically, Wahabi. Wahabi sharia is this: From a Wahabi standpoint, Maliki are takfiri, or apostates, which is hella worse than kafiri, or unbelievers. Know all those poor townfolk that ISIS slaughters en masse without getting confession videos out of 'em first? The ones where all they're good for is bodycount? Those are takfiri. Belgium was attacked by ISIS because there are a lot of kids in ISIS from Belgium.
Maliki school's sources for Sharia are hierarchically prioritized as follows: Quran and then trustworthy Hadiths (sayings, customs and actions of Muhammad); if these sources were ambiguous on an issue, then `Amal (customs and practices of the people of Medina), followed by consensus of the Sahabah (the companions of Muhammad), then individual's opinion from the Sahabah, Qiyas (analogy), Istislah (interest and welfare of Islam and Muslims), and finally Urf (custom of people throughout the Muslim world if it did not contradict the hierarchically higher sources of Sharia).
