Spend, Whatever you speand in Allah's cause, it will be repaid to you

Not upon you, [O Muḥammad], is [responsibility for] their guidance, but Allāh guides whom He wills. And whatever good you [believers] spend is for yourselves, and you do not spend except seeking the face [i.e., approval] of Allāh. And whatever you spend of good¹ - it will be fully repaid to you, and you will not be wronged.

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.

Say, "Indeed, my Lord extends provision for whom He wills of His servants and restricts [it] for him. But whatever thing you spend [in His cause] - He will compensate it; and He is the best of providers."
