﴿ وَمَن كَفَرَ فَلَا يَحْزُنكَ كُفْرُهُۥٓ ۚ إِلَيْنَا مَرْجِعُهُمْ فَنُنَبِّئُهُم بِمَا عَمِلُوٓا۟ ۚ إِنَّ ٱللَّهَ عَلِيمٌۢ بِذَاتِ ٱلصُّدُورِ ﴾

“But as for him who is bent on denying the truth - let not his denial grieve thee: unto Us they must return, and then We shall make them [truly] understand all that they were doing [in life]: for, verily, God has full knowledge of what is in the hearts [of men].”

And whoever disbelieves then do not let his disbelief grieve you O Muhammad (s) do not be concerned with his disbelief. To Us shall be their return and We shall inform them of what they did. Truly God knows best what is in the breasts just as He knows other things and so He will requite them accordingly.
