"The purchase of any item which helps strengthen Zionism is not permissible ..." said Ayatollah Khamenei.

"Each riyal, dirham …etc. used to buy their goods eventually become bullets to be fired at the hearts of brothers and children in Palestine. For this reason, it is an obligation not to help them (the enemies of Islam) by buying their goods. To buy their goods is to support tyranny, oppression and aggression." said Sheikh Yusuf Al Qaradawi.
