432 The "face" (wajh) expresses our personality, our inmost being. White is the colour of Light; to become white is to be illumined with Light, which stands for felicity, the rays of the glorious Light of Allah. Black is the colour of darkness, sin, rebellion, misery; removal from the Grace and Light of Allah. These are the Signs of Heaven and Hell. The standard of decision in all questions is the justice of Allah.
