عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا أَنَّ الصَّعْبَ بْنَ جَثَّامَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ قُلْتُ يَا رَسُولَ اللَّهِ الدَّارُ مِنْ دُورِ الْمُشْرِكِينَ نُصَبِّحُهَا لِلْغَارَةِ فَنُصِيبُ الْوِلْدَانَ تَحْتَ بُطُونِ الْخَيْلِ وَلَا نَشْعُرُ فَقَالَ إِنَّهُمْ مِنْهُمْ
It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that Sayyiduna Sa'b bin Jathamah (may Allah be pleased with him) said: O Messenger of Allah! (Suppose) there is a settlement of polytheists and we launch a sudden attack on it in the morning, and their children are killed under the horses, while we do not realize (who is being killed), then (what will be the ruling regarding the killing of those children)? The Prophet (peace and blessings be upon him) said: Indeed, their children are also from among them.
