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, "Facilitate things to people (concerning religious matters), and do not make it hard for them and give them good tidings and do not make them run away (from Islam)."
