Holy Quran » LUQMAN : 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.

{ ومن كفر فلا يَحزُنْك } يا محمد { كفره } لا تهتم بكفره { إلينا مرجعهم فننبئهم بما عملوا إن الله عليم بذات الصدور } أي بما فيها كغيره فمجاز عليه.
