{4:2} and give to the orphans their property, and do not substitute worthless (things) for (their) good (ones), and do not devour their property (as an addition) to your own property; this is surely a great crime.

{93:9} Therefore, as for the orphan, do not oppress (him).

{4:10} (As for) those who swallow the property of the orphans unjustly, surely they only swallow fire into their bellies and they shall enter burning fire.

{2:220} in this world and the hereafter. And they ask you concerning the orphans Say: To set right for them (their affairs) is good, and if you become co-partners with them, they are your brethren; and Allah knows the mischief-maker and the pacemaker.

{6:152} And do not approach the property of the orphan except in the best manner until he attains his maturity, and give full measure and weight with justice-- We do not impose on any soul a duty except to the extent of its ability; and when you speak, then be just though it be (against) a relative, and fulfill Allah's covenant; this He has enjoined you with that you may be mindful;

{17:34} and draw not near to the property of the orphan except in a goodly way till he attains his maturity and fulfill the promise; surely (every) promise shall be questioned about.
