There is a beauty, a profoundness, a delightfulness in the gaze of those whose hearts are with God. But the gaze of those whose hearts are careless and distant from God gives their true nature away. Almighty God informs us about this in the verse of the Quran: "If We wished, We would show them to you and you would know them by their mark.." What God refers to here by mark is their gaze. The reason behind their purposeless gazes is that their souls are hollow. - Harun Yahya
