Al-Anfaal 8:60

Prepare against them whatever force[35] you can and cavalry, to deter Allah’s enemies and your enemies[36], and others besides them whom you do not know[37], but Allah knows them. Whatever you spend[38] in the cause of Allah will be repaid to you in full, and you will not be wronged.

[35] All types of power: physical, mental as well as weapons. [36] To make them think twice before invading or fighting them.
[37] i.e., lurking enemies.
[38] Funds are necessary for preparing the force.

And prepare against them whatever you are able of power and of steeds of war[456] 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.

[456] Or equipment which serves the same purpose.

60. And make ready against them all you can of power, including steeds of war (tanks, planes, missiles, artillery) to threaten the enemy of Allâh and your enemy, and others besides whom, you may not know but whom Allâh does know. And whatever you shall spend in the Cause of Allâh shall be repaid unto you, and you shall not be treated unjustly.

Make ready for them all thou canst of (armed) force and of horses tethered, that thereby ye may dismay the enemy of Allah and your enemy, and others beside them whom ye know not. Allah knoweth them. Whatsoever ye spend in the way of Allah it will be repaid to you in full, and ye will not be wronged.
