Ask the animals and they will teach you, or the birds of the air and they will tell you; or speak to the earth and it will teach you, or let the fish of the sea inform you. Which of these does not know the hand of God?
From the viewpoint of BELIEFS all doubts are disastrous. From the viewpoint of FAITH, doubt is the indispensable stimulant. To lose one's BELIEFS may not be a loss but a gain: an opportunity. "When the heart weeps for what it has lost, the spirit laughs for what it has gained," is an ancient Sufi saying. To lose one's FAITH, however, is catastrophic; the loss of this vital human constituent means mutilation, dehumanization, cynicism, nihilism.
