Say, `O mankind! I am a Messenger to you all from Allâh to whom belongs the kingdom of the heavens and the earth. There is no other, cannot be and will never be One worthy of worship but He, Who gives life and causes death, so believe in Allâh and in His Messenger, the Arab, the Prophet who believes in Allâh and in (all) His words, and follow him so that you may be rightly guided so as to reach the goal.'
