Call to the way of your Lord with wisdom and goodly exhortation, and have disputations with them in the best manner; surely your Lord best knows those who go astray from His path, and He knows best those who follow the right way.

Allah has revealed the best announcement, a book conformable in its various parts, repeating, whereat do shudder the skins of those who fear their Lord, then their skins and their hearts become pliant to the remembrance of Allah; this is Allah's guidance, He guides with it whom He pleases; and (as for) him whom Allah makes err, there is no guide for him.
