Ali 'Imran 3:123

Walaqad nasarakumu Allahubibadrin waantum athillatun fattaqoo AllahalaAAallakum tashkuroon

And already had Allāh given you victory at [the battle of] Badr while you were weak [i.e., few in number]. Then fear Allāh; perhaps you will be grateful.

Allah certainly supported you at Badr when you were weak. So, fear Allah that you may be grateful
