Pre-Islamic Arabia
Pre-Islamic Arabians used to believe that, while there were multiple "'aalihah" (آلهة, "deities, gods"), only "God" was the "Rabb" (Lord/sustainer) of the earth and heavens. In the Jahiliyyah era of pre-Islamic Arabia, the worship of God was associated with one deity among with other lesser deities, referring to one deity for each of the 365 days in a year and therefore "God" is believed to be an abstract "Supreme Being" who is beyond any resemblance and the one who governs the heavens and earth.
