﴿ فَـَٔامِنُوا۟ بِٱللَّهِ وَرَسُولِهِۦ وَٱلنُّورِ ٱلَّذِىٓ أَنزَلْنَا ۚ وَٱللَّهُ بِمَا تَعْمَلُونَ خَبِيرٌۭ ﴾

“Believe then, [O men,] in God and His Apostle, and in the light [of revelation] which We have bestowed [on you] from on high! And God is fully aware of all that you do.”

So believe in God and His Messenger and the Light the Qur’ān which We have revealed. And God is Aware of what you do.
