"Call to it and follow it as you have been commanded. Do not follow their desires and say: "I believe in the Book which Allah has sent down to me, and I am commanded to do justice among you. Allah is our Lord and your Lord. What we have done is for us and what you have done is for you. There is no dispute between us and you. Allah will bring us together. To Him is the final return."
