﴿ قُلْ إِنِّىٓ أُمِرْتُ أَنْ أَعْبُدَ ٱللَّهَ مُخْلِصًۭا لَّهُ ٱلدِّينَ ﴾

“Say [O Muhammad]: “Behold, I am bidden to worship God, sincere in my faith in Him alone;”

(Say) O Muhammad, to the people of Mecca-this is when they said to him: revert to the religion of our forefathers-: (Lo! I am commanded) in the Qur'an (to worship Allah, making religion pure for Him (only)) and make my worship of Allah and faith in Allah's divine Oneness sincere to Him.
