There has already been a sign for you (O Jews) in the two armies that met (in combat i.e. the battle of Badr): One was fighting in the Cause of Allah, and as for the other (they) were disbelievers. They (the believers) saw them (the disbelievers) with their own eyes twice their number (although they were thrice their number). And Allah supports with His Victory whom He pleases. Verily, in this is a lesson for those who understand. (See Verse 8:44). (Tafsir At-Tabari)
همانا شما را است آیتی در دو سپاه که تلاقی کردند سپاهی که نبرد می‌کرد در راه خدا و دیگری که کافر بود می‌دیدندشان دو برابر خویش به دیدن چشم و خدا است آنکه کمک کند به یاری خود هر که را خواهد همانا در این است پندی از برای خردمندان یا بینایان‌
