Say: Surely, as for me, my Lord has shown me the straight path, a right religion, the creed of Ibrahim, the upright, and he was not of the polytheists. Say: Surely, my prayer and my sacrifice and my living and my dying are for Allah, Lord of the worlds. He has no partner, and this am I commanded, and I am the first of those who submit (to Him). (6:161-163)   Say (O beloved Prophet): Truly, I am commanded to worship Allah, being sincere to Him in obedience. And I am commanded to be the first of those who submit (to Him). (39:11-12)   2. Preacher to all humanity   O mankind! The (Prophetic) Messenger has come to you with the truth from your Lord. Then believe; (it is) better for you. But if you disbelieve, still, surely, to Allah belongs whatsoever is in the heavens and the earth, and Allah is ever Knower, Wise. (4:170)   Blessed is He Who has sent down to His bondman the Criterion (of right and wrong), that he may be a warner to the entire world. (25:1)   And We have not sent you (O beloved Prophet) except as a bringer of good tidings and a warner to all mankind, but most of the people do not know. (34:28)
