بَلَى إِن تَصْبِرُوا وَتَتَّقُوا وَيَأْتُوكُم مِّن فَوْرِهِمْ هَذَا يُمْدِدْكُمْ رَبُّكُم بِخَمْسَةِ آلَافٍ مِّنَ الْمَلَائِكَةِ مُسَوِّمِينَ

Yes, if you are steadfast and Godwary, and should they come at you suddenly, your Lord will aid you with five thousand angels sent in [to the scene of battle].
