And, (O Muslims,) muster up as much might as you can (in the form of weapons and equipment of war) and (also formations) of war steeds (i.e. war mounts to combat) them. Cause terror with this (war readiness) amongst the enemy of Allah and your enemy, and also those besides them whose (secret enmity) you know not; Allah knows them. And whatever you spend in the way of Allah, you will be paid back in full, and you will not be done any injustice.
