Patience (sabr) and piety (taqwā)

بَلَىٰٓ ۚ إِن تَصْبِرُوا۟ وَتَتَّقُوا۟ وَيَأْتُوكُم مِّن فَوْرِهِمْ هَـٰذَا يُمْدِدْكُمْ رَبُّكُم بِخَمْسَةِ ءَالَـٰفٍ مِّنَ ٱلْمَلَـٰٓئِكَةِ مُسَوِّمِينَ

Yes, if you remain patient and conscious of Allāh and they [i.e., the enemy] come upon you [attacking] in rage, your Lord will reinforce you with five thousand angels having marks [of distinction]."
