[Machine] The Messenger of Allah ﷺ sent a detachment on the day of Hunayn and they fought against the polytheists until they killed them and their descendants. When they returned, the Messenger of Allah ﷺ asked them, "What made you kill their descendants?" They replied, "O Messenger of Allah, they were the children of the polytheists." He said, "But are your children any different? By the One in whose hand is the soul of Muhammad, every child is born on the Fitrah (natural inclination towards monotheism) until his tongue expresses it."
أَنَّ رَسُولَ اللهِ ﷺ بَعَثَ سَرِيَّةً يَوْمَ حُنَيْنٍ فَقَاتَلُوا الْمُشْرِكِينَ فَأَفْضَى بِهِمُ الْقَتْلُ إِلَى الذُّرِّيَّةِ فَلَمَّا جَاءُوا قَالَ رَسُولُ اللهِ ﷺ مَا حَمَلَكُمْ عَلَى قَتْلِ الذُّرِّيَّةِ؟ قَالُوا يَا رَسُولَ اللهِ إِنَّمَا كَانُوا أَوْلَادَ الْمُشْرِكِينَ قَالَ أَوَهَلْ خِيَارُكُمْ إِلَّا أَوْلَادُ الْمُشْرِكِينَ وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ مَا مِنْ نَسَمَةٍ تُولَدُ إِلَّا عَلَى الْفِطْرَةِ حَتَّى يُعْرِبَ عَنْهَا لِسَانُهَا
