The Battle of Badr

Quran 3:13:

Already there has been for you a sign in the two armies which met – one fighting in the cause of Allah and another of disbelievers. They saw them [to be] twice their [own] number by [their] eyesight. But Allah supports with His victory whom He wills. Indeed in that is a lesson for those of vision.

The following excerpt is taken from “Maariful Quran” vol 2 pg. 33-34:

This verse refers to the Battle of Badr in which the disbelievers
had about 1000 men, 790 camels and 100 horses, while the Muslim
mujghidh were just over 300, having a total of 70 camels, 2 horses, 6
armours and 8 swords. The encounter was certainly strange as each
combating group saw the opponent being twice its own numbers.. The
sighting of so many Muslims inspired awe in the hearts of the disbelievers, while Muslims who saw the disbelievers as twice of them
turned to Allah more fervently. They had hopes of Allah’s help, and ultimate victory, because they had placed their total trust in Allah, were steadfast and sincerely believed in the promise of Allah revealed to them in the fallowing words:

If there be among you a hundred patient ones, they shall overcome two hundred. (8:66)

If the actual number of disbelievers which was three times more
than their own were to be realized by Muslims, they may have been
overawed. This state of sighting the numbers of the other group as
twice its own was at a particular time. At another time each of the two
combating groups felt the other one as low in numbers, as it would appear later in Surah al-Anfal.
To sum up, it can be safely said that making a small group of people with very little to fight against a much stronger group and score a
victory, as prophecied in Makkah, is an unusual event full of lessons
for the observant and the discerning
