Some Muslims have opined that halal certification is nothing more than a money-making scam, with the most ridiculous aspect being halal certification for dog food. It is ironic that the same imams who declare dogs to be «unclean» animals also willingly charge pet food manufacturers to certify food for the «unclean» beasts to be halal. Other Muslims have conceded that the halal certification scheme has become as financially corrupt as segments of the Jewish kosher product certification system. South African Muslim authorities have pointed out, to the dismay of the halal certification industry, that the Koran forbids imams from charging money to certify food as halal. Yet, the practice continues with fees charged for halal «stamps» on food, in some cases, indirectly propping up various jihadist groups with large sums of ready cash.
