Surah Aali Imran (The Family of Imran), Verse 123

وَلَقَدْ نَصَرَكُمُ اللّٰهُ بِبَدْرٍ وَّاَنْتُمْ اَذِلَّةٌ فَاتَّقُوا اللّٰهَ لَعَلَّكُمْ تَشْكُرُوْنَ ۟

Wa laqad nasarakumul laahu bi-Badrinw wa antum azillatun fattaqul laaha la'allakum tashkuroon

“Allah had helped you at Badr, when ye were a contemptible little force; then fear Allah; thus May ye show your gratitude.”
