Sometimes it happens that some guardians of the orphans, under the pretext that changing the property of the orphan is benefit able for the orphan, or it makes no difference to change it, or if it remains it will be wasted, take the best and choice parts of the properties of the orphans and put their own bad and undemanded properties in their places. The Qur'an says: "...
and do not exchange something bad (of yours) for something good (of theirs)..." The third instruction has been added as follows: "... nor devour their property along with your own..." This sentence means that: do not mix the property of the orphans with your own property so that its result ends to the possession of the whole. Or, do not mix your undesirable property with their good property so that its result be treading the rights of the orphans.
"And, if you fear that you cannot act equitably towards orphans, then marry those women who seem good to you, two, or three, or four; but if you (still) fear that you will not act justly (between them) then ( marry ) only one or someone your right hands have acquired.
That is more proper, that you may not deviate from equity." Occasion of Revelation Before Islam, it was customary in Arabia among many people that they took the orphan girls to their houses under the name of defraying and guardianship and then they married them and appropriated their property, too. They assigned even their dowries less than what the ordinary amount was, since everything was in their own hand, and when they felt the least inconvenience from them, they would easily leave them off.
At that time the verse was revealed and instructed the guardians of the orphans that they could marry the girl orphans if they observed justice about them completely. In this verse, another right, out of the rights of the orphans, is pointed out.
