آل عمران
بَلَىٰ ۚ إِن تَصْبِرُوا وَتَتَّقُوا وَيَأْتُوكُم مِّن فَوْرِهِمْ هَٰذَا يُمْدِدْكُمْ رَبُّكُم بِخَمْسَةِ آلَافٍ مِّنَ الْمَلَائِكَةِ مُسَوِّمِينَ 125
Also in this battle of Ohud, if you be patient and stay firm, and avoid evil, Allah may sent down five thousands of the angels marked down to help you.
