سورة آل عمران

بَلَىٰ ۚ إِنْ تَصْبِرُوا وَتَتَّقُوا وَيَأْتُوكُمْ مِنْ فَوْرِهِمْ هَٰذَا يُمْدِدْكُمْ رَبُّكُمْ بِخَمْسَةِ آلَافٍ مِنَ الْمَلَائِكَةِ مُسَوِّمِينَ ﴿١٢٥﴾

Surah Aali 'Imran

125. Most certainly. But if you persevere and remain cautious, and they attack you suddenly, your Lord will reinforce you with five thousand angels, well trained.
