Measures

Give full measure and weight in fairness. Do not defraud people of their rights. That is best and leads to the best outcome.

6:152And approach not the wealth of the orphan save with that which is better, till he reach maturity. Give full measure and full weight, in justice. We task not any soul beyond its scope. And if ye give your word, do justice thereunto, even though it be (against) a kinsman; and fulfil the covenant of Allah. This He commandeth you that haply ye may remember.

11:85O my people! Give full measure and full weight in justice, and wrong not people in respect of their goods. And do not evil in the earth, causing corruption.

17:35Fill the measure when ye measure, and weigh with a right balance; that is meet, and better in the end.

26:181Give full measure, and be not of those who give less (than the due).
