Narrated Ibn `Abbas:
حَدَّثَنَا حِبَّانُ ، أَخْبَرَنَا عَبْدُ اللَّهِ ، أَخْبَرَنَا شُعْبَةُ ، عَنْ أَبِي بِشْرٍ ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهم ـ قَالَ سُئِلَ رَسُولُ اللَّهِ صلى الله عليه وسلم عَنْ أَوْلاَدِ الْمُشْرِكِينَ فَقَالَ " اللَّهُ إِذْ خَلَقَهُمْ أَعْلَمُ بِمَا كَانُوا عَامِلِينَ " .
Allah's Messenger (ﷺ) (p.b.u.h) was asked about the children of (Mushrikeen) pagans. The Prophet (ﷺ) replied, "Since Allah created them, He knows what sort of deeds they would have done."
