In the name of Allah, the most Gracious, the most Merciful

(2:220) To this world and the Hereafter. And they ask you about orphans. Say, “Improvement for them is best. And if you mix your affairs with theirs – they are your brothers. And Allah knows the corruptor from the amender. And if Allah had willed, He could have put you in difficulty. Indeed, Allah is Exalted in Might and Wise.

(4:2) And give to the orphans their properties and do not substitute the defective [of your own] for the good [of theirs]. And do not consume their properties into your own. Indeed, that is ever a great sin.
(4:3) And if you fear that you will not deal justly with the orphan girls, then marry those that please you of [other] women, two or three or four. But if you fear that you will not be just, then [marry only] one or those your right hand possesses. That is more suitable that you may not incline [to injustice].
(4:4) And give the women [upon marriage] their [bridal] gifts graciously. But if they give up willingly to you anything of it, then take it in satisfaction and ease.
(4:5) And do not give the weak-minded your property, which Allah has made a means of sustenance for you, but provide for them with it and clothe them and speak to them words of appropriate kindness.
(4:6) And test the orphans [in their abilities] until they reach marriageable age. Then if you perceive in them sound judgment, release their property to them. And do not consume it excessively and quickly, [anticipating] that they will grow up. And whoever, [when acting as guardian], is self-sufficient should refrain [from taking a fee]; and whoever is poor – let him take according to what is acceptable. Then when you release their property to them, bring witnesses upon them. And sufficient is Allah as Accountant.

(4:127) And they request from you a [legal] ruling concerning women. Say, “Allah gives you a ruling about them and [about] what has been recited to you in the Book concerning the orphan girls to whom you do not give what is decreed for them – and [yet] you desire to marry them – and concerning the oppressed among children and that you maintain for orphans [their rights] in justice.” And whatever you do of good – indeed, Allah is ever Knowing of it.

(6:151) Say, “Come, I will recite what your Lord has prohibited to you. [He commands] that you not associate anything with Him, and to parents, good treatment, and do not kill your children out of poverty; We will provide for you and them. And do not approach immoralities – what is apparent of them and what is concealed. And do not kill the soul which Allah has forbidden [to be killed] except by [legal] right. This has He instructed you that you may use reason.”
(6:152) And do not approach the orphan’s property except in a way that is best until he reaches maturity. And give full measure and weight in justice. We do not charge any soul except [with that within] its capacity. And when you testify, be just, even if [it concerns] a near relative. And the covenant of Allah fulfill. This has He instructed you that you may remember.
(6:153) And, [moreover], this is My path, which is straight, so follow it; and do not follow [other] ways, for you will be separated from His way. This has He instructed you that you may become righteous.

(17:34) And do not approach the property of an orphan, except in the way that is best, until he reaches maturity. And fulfill [every] commitment. Indeed, the commitment is ever [that about which one will be] questioned.
(17:35) And give full measure when you measure, and weigh with an even balance. That is the best [way] and best in result.
(17:36) And do not pursue that of which you have no knowledge. Indeed, the hearing, the sight and the heart – about all those [one] will be questioned.

(93:9) So as for the orphan, do not oppress [him].
(93:10)And as for the petitioner, do not repel [him].
(93:11) But as for the favor of your Lord, report [it].
