It is but Satan who instils [into you] fear of his allies: so fear them not, but fear Me, if you are [truly] believers!
Al-Imran (The Family of Imran) Verse 175
The Prophet said, "Faith (Belief) consists of more than sixty branches (i.e. parts). And Haya (This term "Haya" covers a large number of concepts which are to be taken together; amongst them are self respect, modesty, bashfulness, and scruple, etc.) is a part of faith."
