If you have been praying for victory, [O believers] - victory has now indeed come unto you. And if you abstain [from sinning], it will be for your own good; but if you revert to it, We shall revoke [Our promise of aid] - and never will your community be of any avail to you, however great its numbers: for, behold, God is [only] with those who believe !
Al-Anfal (The Spoils of War) Verse 19
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."
