And prepare against them whatever you are able of power and of steeds of war1 by which you may terrify the enemy of Allāh and your enemy and others besides them whom you do not know [but] whom Allāh knows. And whatever you spend in the cause of Allāh will be fully repaid to you, and you will not be wronged.
Prepare, O believers, whatever numbers and war equipment you are able to, including keeping trained horses to be used in Allah’s path, so you can frighten Allah’s enemies and your enemies from among the disbelievers who are eagerly waiting for you to be afflicted with a disaster. You can also frighten others whom you do not know of and whose hidden hatred you are not aware of. Allah alone knows them and He knows what they keep hidden inside themselves. Any wealth you spend, whether a little or much, Allah will replace it for you in this world and will give you the reward for it in full in the Afterlife without any reduction. So hurry towards spending in His path.
