In this Surah Allah says :
1.Say (O Muhammad (Peace be upon him)to these Mushrikûn and Kâfirûn): “O Al-Kâfirûn (disbelievers in Allâh, in His Oneness, in His Angels, in His Books, in His Messengers, in the Day of Resurrection, and in Al-Qadar, etc.)!
2.”I worship not that which you worship,
3.”Nor will you worship that which I worship.
4.”And I shall not worship that which you are worshiping.
5.”Nor will you worship that which I worship.
6.”To you be your religion, and to me my religion (Islâmic Monotheism).”
