Encouraged to Fight

Now Allah has lightened your burden, knowing that there is weakness among you. If one hundred remain steadfast, they will overcome two hundred; and if one thousand remain steadfast, they will overcome two thousand, by Allah’s permission. Allah is with the steadfast.

8:66Now hath Allah lightened your burden, for He knoweth that there is weakness in you. So if there be of you a steadfast hundred they shall overcome two hundred, and if there be of you a thousand (steadfast) they shall overcome two thousand by permission of Allah. Allah is with the steadfast.
