Muslims kneel down, kissing and pray towards the black stone,( kaaba') in mecca. Is it an idol worship??

Allah is the moon god of Arabian Pagan worship. Thus it is a sin to kneel to Allah. Interestingly, not many Muslims want to accept that Allah was already being worshipped at the Ka'ba in Mecca by Arab pagans before Muhammad came. Some Muslims become angry when they are confronted with this fact. But history is not on their side."But history establishes beyond the shadow of doubt that even the pagan Arabs, before Muhammad’s time, knew their chief god by the name of Allah and even, in a sense, proclaimed his unity...Among the pagan Arabs this term denoted the chief god of their pantheon, the Kaaba, with its three hundred and sixty idols."
