Those who do not know Allah they worship Him just like that in misguidance.” I then asked, may Allah take my soul in service for your cause, what the knowledge about Allah?” The Imam (a.s.) said, “Knowledge about Allah means is to acknowledge the existence of Allah, the Most Holy, the Most High, to acknowledge His messenger and to love Imam Ali (a.s.). Of such knowledge is to follow him and the Imams of guidance and to denounce before Allah, the Most Holy, the Most High, their (Imams’) enemies. This is how the knowledge about Allah is.”
