[And give] unto [such of] the needy who, being wholly wrapped up in God's cause, are unable to go about the earth [in search of livelihood].* He who is unaware [of their condition] might think that they are wealthy, because they abstain [from begging]; [but] thou canst recognize them by their special mark: they do not beg of men with importunity. And whatever good you may spend [on them], verily, God knows it all.
And test the orphans [in your charge] until they reach a marriageable age; then, if you find them to be mature of mind, hand over to them their possessions; and do not consume them by wasteful spending, and in haste, ere they grow up. And let him who is rich abstain entirely [from his ward's property]; and let him who is poor partake thereof in a fair manner. And when you hand over to them their possessions, let there be witnesses on their behalf - although none can take count as God does.
And as for those who are unable to marry,* let them live in continence until God grants them sufficiency out of His bounty, And if any of those whom you rightfully possess* desire [to obtain] a deed of freedom, write it out for them if you are aware of any good in them:* and give them [their share of the wealth of God which He has given you.* And do not, in order to gain* some of the fleeting pleasures of this worldly life, coerce your [slave] maidens into whoredom if they happen to be desirous of marriage;* and if anyone should coerce them, then, verily, after they have been compelled [to submit in their helplessness], God will be much-forgiving, a dispenser of grace!
AND* [know that] women advanced in years, who no longer feel any sexual desire,* incur no sin if they discard their [outer] garments, provided they do not aim at a showy display of [their] charms. But [even so,] it is better for them to abstain [from this]: and God is all-hearing, all-knowing.
