Fajr is a sign of the rising of the sun, so it is like the divine name in that it denotes the one called by it, not the meaning by which it is distinguished from other names. The one who intends to fast may intend it out of necessity and choice, and the person, in his knowledge of God, may be the possessor of intellectual insight or the possessor of witnesses. His knowledge of God came from looking at evidence, so he must seek the evidence that leads him to knowledge. He is in the same position as someone who made an intention before dawn, and the period of his looking at evidence is like the period from dawn to sunrise .
