Hadith 23:136
Narrated Ibn `Abbas:
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."
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 "
