None is Worthy of Worship but He

Allah (Himself) bears witness that none is worthy of worship but He, and (so do) the angels and those having knowledge, Maintaining His creation with justice; none is worthy of worship but He, the Mighty, the Wise. (3:18)

A mercy from your Lord, surely He is the All-Hearing, the All-Knowing.
The Lord of the heavens and the earth and what is between them, if you have certainty.
None is to be worshipped but He; He gives life and causes death; your Lord and the Lord of your forefathers. (44:6-8)
