From the Holy Qur'an:Chapter 11 - Hood P1/2

“You shall not worship except God.” I come to you from Him as a warner, as well as a bearer of good news. You shall seek your Lord’s forgiveness, then repent to Him. He will then bless you generously for a predetermined period, and bestow His grace upon those who deserve it. To God is your ultimate return, and He is Omnipotent. His (earthy) domain was completely covered with water- in order to test you, to distinguish those among you who work righteousness. God controls all things.
