Divine support and intervention for the believers

وَأَنزَلَ ٱلَّذِينَ ظَـٰهَرُوهُم مِّنْ أَهْلِ ٱلْكِتَـٰبِ مِن صَيَاصِيهِمْ وَقَذَفَ فِى قُلُوبِهِمُ ٱلرُّعْبَ فَرِيقًا تَقْتُلُونَ وَتَأْسِرُونَ فَرِيقًا

And He brought down those who supported them among the People of the Scripture from their fortresses and cast terror into their hearts [so that] a party [i.e., their men] you killed, and you took captive a party [i.e., the women and children].
