عَنِ الْأَسْوَدِ بْنِ سَرِيعٍ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ بَعَثَ سَرِيَّةً يَوْمَ حُنَيْنٍ فَقَاتَلُوا الْمُشْرِكِينَ فَأَفْضَى بِهِمُ الْقَتْلُ إِلَى الذُّرِّيَّةِ فَلَمَّا جَاءُوا قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ مَا حَمَلَكُمْ عَلَى قَتْلِ الذُّرِّيَّةِ قَالُوا يَا رَسُولَ اللَّهِ 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
It is narrated from Sayyiduna Aswad bin Sari’ (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) sent a detachment on the day of Hunayn. They fought against the polytheists, and the killing extended to children and women. When they returned, the Messenger of Allah (peace and blessings be upon him) said: What made you kill children and women? They said: O Messenger of Allah! They are the offspring of the polytheists. The Prophet (peace and blessings be upon him) said: Are not your favorite individuals also the offspring of polytheists? By Him in Whose hand is the soul of Muhammad (peace and blessings be upon him)! Every soul is born upon the natural disposition of Islam, until its tongue makes it clear otherwise.
