Al-Anfaal (The Spoils of War)

45. “O you who have Faith! when you encounter a host (in battle), then stand firm, and remember Allah much, that you may be prosperous.”

Now that Allah (s.w.t,) has commanded the Muslims to be steadfast in the battlefield, He says:

“O you who have Faith! when you encounter a host (in battle), then stand firm...”

That is, whenever you face with a group of infidels in war, stand firm for fighting against them, and do not escape. And, it is evident that believers generally do not fight save against hostile infidels.

Then the holy verse implies that, at the time of war, Muslims should seek help from Allah, the Mighty, so that not only they become victorious and successful in the present world but also they become prosperous in the coming world. The verse continues saying:

“...and remember Allah much, that you may be prosperous.”

Some commentators say that this part of the verse means that you should remember the promises of Allah, which He has given you about triumph, in order that your steadfastness might he increased.
