Thus heart is the place of Divine Glance (Al-Nadhr)…how strange! A person is more concerned about looking after the face which is the place of the glances of the creation (ie which is seen by the people), he washes it and removes dirt from it and he tries his best to beautify it so that people do not see any defects (of the face). However, he is careless regarding the heart which is under the Divine Glance. He doesn’t clean it, nor does he beautify it for Allāh’s sake. Rather he leaves it full of dirt (dirty) so much so that if people were to become aware of the dirt of his heart they would leave him and reject him….
