Already there has been for you a sign in the two armies which met [in combat at Badr] - one fighting in the cause of Allāh and another of disbelievers. They saw them [to be] twice their [own] number by [their] eyesight. But Allāh supports with His victory whom He wills. Indeed in that is a lesson for those of vision.
— Saheeh International
You have already seen a sign in the two armies that met in battle, one fighting for God’s cause and the other made up of disbelievers. With their own eyes [the former] saw [the latter] to be twice their number, but God helps whoever He will. There truly is a lesson in this for all with eyes to see.’
— M. A. S. Abdel Haleem
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 Allâh, 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 Allâh supports with His Victory whom He wills. Verily, in this is a lesson for those who understand. (See Verse 8:44). (Tafsir At-Tabarî)
