To make them walk in the right way is not incumbent on you, but Allah guides aright whom He pleases; and whatever good thing you spend, it is to your own good; and you do not spend but to seek Allah's pleasure; and whatever good things you spend shall be paid back to you in full, and you shall not be wronged.

And to Madyan (We sent) their brother Shu'aib. He said: O my people! serve Allah, you have no god other than Him; clear proof indeed has come to you from your Lord, therefore give full measure and weight and do not diminish to men their things, and do not make mischief in the land after its reform; this is better for you if you are believers:

And when he furnished them with their provision, he said: Bring to me a brother of yours from your father; do you not see that I give full measure and that I am the best of hosts?

And give full measure when you measure out, and weigh with a true balance; this is fair and better in the end.
