Surah Aal-i-Imraan 3:125 — سُورَةُ آلِ عِمۡرَانَ

بَلَىٰٓ ۚ إِن تَصْبِرُوا۟ وَتَتَّقُوا۟ وَيَأْتُوكُم مِّن فَوْرِهِمْ هَٰذَا يُمْدِدْكُمْ رَبُّكُم بِخَمْسَةِ ءَالَٰفٍۢ مِّنَ ٱلْمَلَٰٓئِكَةِ مُسَوِّمِينَ ﴿125﴾

Nay, but if ye persevere, and keep from evil, and (the enemy) attack you suddenly, your Lord will help you with five thousand angels sweeping on.
