An-Nisa' (The Women)
Surah 4 · Verse 104
And do not be weak hearted in the pursuit of the (enemys) people, if you are in pain then they too are in pain as you are in pain, and you hope from Allah that which they do not hope for, and Allah is Knowing, Wise. (R 15)
The enemy is to be pursued boldly. Both the parties suffer, but the believers hope to achieve paradise where as the infidels do not.
