Heavenly commandment for the betterment of societies

O you who believe! Stand out firmly for justice, as witnesses to Allâh, even though it be against yourselves, or your parents, or your kin, be he rich or poor, Allâh is a Better Protector to both (than you). So follow not the lusts (of your hearts), lest you avoid justice, and if you distort your witness or refuse to give it, verily, Allâh is Ever Well¬Acquainted with what you do

An-Nisa 135

Ethical Commandments for the benefit of society

Worship Allâh and join none with Him (in worship), and do good to parents, kinsfolk, orphans, Al-Masâkin (the poor), the neighbour who is near of kin, the neighbour who is a stranger, the companion by your side, the wayfarer (you meet), and those (slaves) whom your right hands possess. Verily, Allâh does not like such as are proud and boastful;
An-Nisa 36

Guidelines about returning the property to orphans

And try orphans (as regards their intelligence) until they reach the age of marriage; if then you find sound judgement in them, release their property to them, but consume it not wastefully, and hastily fearing that they should grow up, and whoever (amongst guardians) is rich, he should take no wages, but if he is poor, let him have for himself what is just and reasonable (according to his labour). And when you release their property to them, take witness in their presence; and Allâh is All¬Sufficient in taking account.

An-Nisa 6

Permission of 4 wives simultaneously

And if you fear that you shall not be able to deal justly with the orphan¬girls, then marry (other) women of your choice, two or three, or four but if you fear that you shall not be able to deal justly (with them), then only one or (slaves) that your right hands possess. That is nearer to prevent you from doing injustice.

And give to the women (whom you marry) their Mahr (obligatory bridal-money given by the husband to his wife at the time of marriage) with a good heart, but if they, of their own good pleasure, remit any part of it to you, take it, and enjoy it without fear of any harm (as Allâh has made it lawful).

An-Nisa 3-4

Don't oppress orphans

And give unto orphans their property and do not exchange (your) bad things for (their) good ones; and devour not their substance (by adding it) to your substance. Surely, this is a great sin.

And if you fear that you shall not be able to deal justly with the orphan¬girls, then marry (other) women of your choice, two or three, or four but if you fear that you shall not be able to deal justly (with them), then only one or (slaves) that your right hands possess. That is nearer to prevent you from doing injustice.

And give to the women (whom you marry) their Mahr (obligatory bridal-money given by the husband to his wife at the time of marriage) with a good heart, but if they, of their own good pleasure, remit any part of it to you, take it, and enjoy it without fear of any harm (as Allâh has made it lawful).

Comment
This verse refers to the case where an orphan girl is under the custody of a person and his custodian/guardian wants to marry her with the intention to eat up her property and doesn't pay her the mahr as much as she is being offered by other candidates or it is expected that she'll be given an offer more than that.

Merits of Politeness

And by the Mercy of Allâh, you dealt with them gently. And had you been severe and harsh hearted, they would have broken away from about you; so pass over (their faults), and ask (Allâh's) Forgiveness for them; and consult them in the affairs. Then when you have taken a decision, put your trust in Allâh, certainly, Allâh loves those who put their trust (in Him).

Aal e Imran 159

Dont eat up properties of each other !

And eat up not one another's property unjustly (in any illegal way e.g. stealing, robbing, deceiving, etc.), nor give bribery to the rulers (judges before presenting your cases) that you may knowingly eat up a part of the property of others sinfully
Al Baqarah 188

Solution to world's financial crisis

Deal not unjustly (by asking more than your capital sums), and you shall not be dealt with unjustly (by receiving less than your capital sums).

Verse 279 Chapter AL Baqarah
Translation by Dr. Mohsin

Allâh will destroy Ribâ (usury) and will give increase for Sadaqât (deeds of charity, alms, etc.) And Allâh likes not the disbelievers, sinners.

Al Baqarah

O you who believe! Eat not Ribâ (usury) doubled and multiplied, but fear Allâh that you may be successful.
And fear the Fire, which is prepared for the disbelievers.
And obey Allâh and the Messenger (Muhammad SAW) that you may obtain mercy

Aal eImran 130-132

Comment

Currently the financial system of the whole world is a fraudulent system.It is mere fraud.Paper money ahs no value.Allah says in Quran:

"And don't eat the properties of each other by wong means (i.e don't usurp each others properties)"

Since the present financial system of the world ensures a fraud to the masses and the exploitation of the poor by means of usuary etc. it is cursed forever and it will remain cursed forever .No one can come against the Divine Power.The world can't get out of this situation unless and until it rejects this financial system of oppression

Heavenly Warning to avoid Financial Crisis

Deal not unjustly (by asking more than your capital sums), and you shall not be dealt with unjustly (by receiving less than your capital sums).
