"The Messenger of Allah was asked about the children of the idolators and he said: 'Allah created them when He created them, and He knows best what they would have done."' (Using translation from Nasāʾī 1951)
سُئِلَ رَسُولُ اللهِ ﷺ عَنْ أَوْلَادِ الْمُشْرِكِينَ فَقَالَ «خَلَقَهُمُ اللهُ حِينَ خَلَقَهُمْ وَهُوَ يَعْلَمُ مَا كَانُوا عَامِلِينَ»
