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, "A Muslim is the one who avoids harming Muslims with his tongue and hands. And a Muhajir (emigrant) is the one who gives up (abandons) all what Allah has forbidden."
