God has granted you victory at Badr, despite your weakness. Therefore, you shall observe God, to show your appreciation.
وَلَقَد نَصَرَكُمُ اللَّهُ بِبَدرٍ وَأَنتُم أَذِلَّةٌ فَاتَّقُوا اللَّهَ لَعَلَّكُم تَشكُرونَ
wa laqad nasarakumul laahu bi-Badrinw wa antum azillatun fattaqul laaha la’allakum tashkuroon
