ELI5: How Middle East terrorists groups makes money?

I've heard that that central american terrorists groups make money throughout drugs, but I've never heard how middle east terrorists groups make money and sustain themselves.

Depends on the groups. 

- Donations from countries like Iran, Saudi arabia, UAE,

- Extorsion and protection money

- small and medium businesses (hezbullah was found to even been peddling used cars)

- Investment banking. 

- Drugs and weapons, While they do prohibit their consumption, selling them to non muslims seem to be ok.
