Surah Az-Zumar — Ayah 2 (39:2)
إِنَّآ أَنزَلۡنَآ إِلَيۡكَ ٱلۡكِتَٰبَ بِٱلۡحَقِّ فَٱعۡبُدِ ٱللَّهَ مُخۡلِصٗا لَّهُ ٱلدِّينَ ٢
English translation (Saheeh International)
Indeed, We have sent down to you the Book, [O Muḥammad], in truth. So worship Allāh, [being] sincere to Him in religion.
Brief commentary
O Messenger, I revealed the Qur’ān to you which comprises the truth, so all of its news are true and all of its rulings are just. So worship Allah, declaring Him to be One, directing all of your acts of worship to only Him.
