O men! Be conscious of your Sustainer: for, verily the violent convulsion of the Last Hour will be an awesome thing!
Al-Hajj (The Pilgrimage) Verse 1
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."
