﴿ إِنَّآ أَنزَلْنَآ إِلَيْكَ ٱلْكِتَٰبَ بِٱلْحَقِّ فَٱعْبُدِ ٱللَّهَ مُخْلِصًۭا لَّهُ ٱلدِّينَ ﴾

“for, behold, it is We who have bestowed this revela­tion upon thee from on high, setting forth the truth: so worship Him, sincere in thy faith in Him alone!”

Indeed We have revealed to you O Muhammad (s) the Book with the truth bi’l-haqqi is semantically connected to anzalnā ‘We have revealed’; so worship God devoting your religion purely to Him pure of any idolatry in other words affirming His Oneness.
