وَمَنْ كَفَرَ فَلَا يَحْزُنْكَ كُفْرُهٗۗ اِلَيْنَا مَرْجِعُهُمْ فَنُنَبِّئُهُمْ بِمَا عَمِلُوْاۗ اِنَّ اللّٰهَ عَلِيْمٌۢ بِذَاتِ الصُّدُوْرِ ( لقمان: ٢٣ )
Wa man kafara falaa yahzunka kufruh; ilainaa marji'uhum fanunabbi'uhum bimaa 'amiloo; innal laaha 'aleemum bizaatis sudoor (Luq̈mān 31:23)
And whoever has disbelieved – let not his disbelief grieve you. To Us is their return, and We will inform them of what they did. Indeed, Allah is Knowing of that within the breasts. (Luqman  : 23)

And whoever disbelieves, let not his disbelief grieve you. To Us is their return. Then We will tell them what they did. Surely, Allah is All Aware of what lies in the hearts.
