The mark of God, that is, we believe in God and He has marked us with a [particular] mark. Every adherent of a belief or a creed is marked inwardly by the mark of his belief, religion or creed. The adherents of the different creeds are all marked by the mark of their intentions; the adherents of schools of thought [are marked] by the mark of their imam and leader; the philosophers by the mark of their intellects; the various heretics and the innovators [are marked] by the mark of their heresies and souls, while the affirmers of God's Oneness [are marked] specifically by the mark of God, better than which there is no mark and beyond which there can be no other mark, as the Messenger of God said: 'Verily God created [His] creatures in darkness, then sprinkled upon them of His light and whoever was touched by that light was guided and whoever it missed went astray: that light then is His mark; [and who has a better mark than God? And Him we worship.]
