Do not approach the property of the orphan, except with the best possible conduct, until he reaches maturity. Give full measure and full weight in all fairness – We do not obligate anyone beyond his capacity – and be just when you speak, even though the one (against whom you are speaking) is a relative; and fulfill the covenant of Allah. This is what He has enjoined upon you, so that you may observe the advice.
(Remember) when We took a pledge from the children of Isra‘il (Israel): :You shall not worship anyone other than Allah; and you shall do good to the parents, and to near of kin, and to orphans and the needy. And say to the people what is good, and be steadfast in Salah (prayer), and pay Zakah . Then, you went back (on your word), all but a few among you, and you are used to turning away.

O you who believe, abstain from many of the suspicions. Some suspicions are sins. And do not be curious (to find out faults of others), and do not backbite one another. Does one of you like that he eats the flesh of his dead brother? You would abhor it. And fear Allah. Surely Allah is Most-Relenting, Very-Merciful.
