(Yet they ascribe as partners unto Him the jinn…) [6:100].
Al-Kalbi said: “This verse was revealed about the atheists who claimed that Allah and Satan were two brothers; that Allah was the creator of human beings, beasts and cattle whereas Satan was the creator of vipers, predatory animals and scorpions. Hence Allah’s saying (Yet they ascribe as partners unto Him the jinn)”.
