It was narrated from Ibn ‘Abbas: “And certainly, the Shayatin (devils) do inspire their friends (from mankind).” [6:121] He said: “They used to say: ‘Whatever the Name of Allah has been mentioned over, do not eat it, and whatever the Name of Allah has not been mentioned over, eat it.’ Then Allah said: “Eat not of that over which Allah’s Name has not been pronounced.’” [6:121]
It was narrated from ‘Aishah, the Mother of the Believers, that some people said: “O Messenger of Allah, some people bring us meat, and we do not know whether the Name of Allah has been mentioned over it or not.” He said: “Say: Bismillah and eat.’ They were new in Islam.
