Deen e Hanif (Islam) has always been provoking the value of a human being

Because of that We ordained for the Children of Israel that if anyone killed a person not in retaliation of murder, or (and) to spread mischief in the land - it would be as if he killed all mankind, and if anyone saved a life, it would be as if he saved the life of all mankind. And indeed, there came to them Our Messengers with clear proofs, evidences, and signs, even then after that many of them continued to exceed the limits (e.g. by doing oppression unjustly and exceeding beyond the limits set by Allâh by committing the major sins) in the land!

al maeda 32

If you commit a sin,seek repentance and dont mention it openly

Then Allâh sent a crow who scratched the ground to show him to hide the dead body of his brother. He (the murderer) said: "Woe to me! Am I not even able to be as this crow and to hide the dead body of my brother?" Then he became one of those who regretted.

Al maeda 31

Help in porvoking righteousness

Help each other in righteousness and piety, and do not help each other in sin and aggression. Fear Allah. Surely, Allah is severe at punishment.

Al maeda 2

Guidelines for the inheritance in case of kalalah

They ask you for a legal verdict. Say: "Allâh directs (thus) about Al¬Kalâlah (those who leave neither descendants nor ascendants as heirs). If it is a man that dies, leaving a sister, but no child, she shall have half the inheritance. If (such a deceased was) a woman, who left no child, her brother takes her inheritance. If there are two sisters, they shall have two-thirds of the inheritance; if there are brothers and sisters, the male will have twice the share of the female. (Thus) does Allâh makes clear to you (His Law) lest you go astray. And Allâh is the All-Knower of everything."

An-Nisa 176

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

Heavenly principle for the benefit of societies

If you fear a breach between them twain (the man and his wife), appoint (two) arbitrators, one from his family and the other from her's; if they both wish for peace, Allâh will cause their reconciliation. Indeed Allâh is Ever All¬Knower, Well¬Acquainted with all things.

An-Nisa 35

Comparison of social status of men and women

Men are the protectors and maintainers of women, because Allâh has made one of them to excel the other, and because they spend (to support them) from their means. Therefore the righteous women are devoutly obedient (to Allâh and to their husbands), and guard in the husband's absence what Allâh orders them to guard (e.g. their chastity, their husband's property). As to those women on whose part you see ill¬conduct, admonish them (first), (next), refuse to share their beds, (and last) beat them (lightly, if it is useful), but if they return to obedience, seek not against them means (of annoyance). Surely, Allâh is Ever Most High, Most Great

An-Nisa 34

Dont eat up properties

O you who believe! Eat not up your properties among yourselves unjustly except it be a trade amongst you, by mutual consent. And do not kill yourselves (nor kill one another). Surely, Allâh is Most Merciful to you.
And whoever commits that through aggression and injustice, We shall cast him into the Fire, and that is easy for Allâh.
If you avoid the great sins[] which you are forbidden to do, We shall expiate from you your (small) sins, and admit you to a Noble Entrance (i.e. Paradise).
An-Nisa 29-31

Relatives which can't be married

And marry not women whom your fathers married, except what has already passed; indeed it was shameful and most hateful, and an evil way.

Forbidden to you (for marriage) are: your mothers, your daughters, your sisters, your father's sisters, your mother's sisters, your brother's daughters, your sister's daughters, your foster mother who gave you suck, your foster milk suckling sisters, your wives' mothers, your step daughters under your guardianship, born of your wives to whom you have gone in - but there is no sin on you if you have not gone in them (to marry their daughters), - the wives of your sons who (spring) from your own loins, and two sisters in wedlock at the same time, except for what has already passed; verily, Allâh is Oft¬Forgiving, Most Merciful.

An-Nisa 22-23

Quranic guidelines for inheritance

Allâh commands you as regards your children's (inheritance); to the male, a portion equal to that of two females; if (there are) only daughters, two or more, their share is two thirds of the inheritance; if only one, her share is half. For parents, a sixth share of inheritance to each if the deceased left children; if no children, and the parents are the (only) heirs, the mother has a third; if the deceased left brothers or (sisters), the mother has a sixth. (The distribution in all cases is) after the payment of legacies he may have bequeathed or debts. You know not which of them, whether your parents or your children, are nearest to you in benefit, (these fixed shares) are ordained by Allâh. And Allâh is Ever All¬Knower, All¬Wise.

In that which your wives leave, your share is a half if they have no child; but if they leave a child, you get a fourth of that which they leave after payment of legacies that they may have bequeathed or debts. In that which you leave, their (your wives) share is a fourth if you leave no child; but if you leave a child, they get an eighth of that which you leave after payment of legacies that you may have bequeathed or debts. If the man or woman whose inheritance is in question has left neither ascendants nor descendants, but has left a brother or a sister, each one of the two gets a sixth; but if more than two, they share in a third; after payment of lagacies he (or she) may have bequeathed or debts, so that no loss is caused (to anyone). This is a Commandment from Allâh; and Allâh is Ever All¬Knowing, Most¬Forbearing.

These are the limits (set by) Allâh (or ordainments as regards laws of inheritance), and whosoever obeys Allâh and His Messenger (Muhammad SAW) will be admitted to Gardens under which rivers flow (in Paradise), to abide therein, and that will be the great success.

And whosoever disobeys Allâh and His Messenger (Muhammad SAW), and transgresses His limits, He will cast him into the Fire, to abide therein; and he shall have a disgraceful torment.

An-Nisa 11-14

Warning to guardians to fear Allah

And let those (executors and guardians) have the same fear in their minds as they would have for their own, if they had left weak offspring behind. So let them fear Allâh and speak right words.

Verily, those who unjustly eat up the property of orphans, they eat up only a fire into their bellies, and they will be burnt in the blazing Fire!

An-Nisa 9-10

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

Dont make your wives the custodian of the property

And give not unto the foolish your property which Allâh has made a means of support for you, but feed and clothe them therewith, and speak to them words of kindness and justice.

An-Nisa 5

Comment
In this verse women i.e wives are meant by foolish in the opinion of Ibn e Abbas R.A ,Ibn e Masood,Mujahid,Qatadah R.A and many others.Our social observations proof that women are more extravagant than men and they cant guard the propertya s effectively as men themselves ,therefor it is not wise to give them the custody of the property.

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.

An-Nisa 2-4

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.

Dont cut the relations with kins

O mankind! Be dutiful to your Lord, Who created you from a single person (Adam), and from him (Adam) He created his wife [Hawwa (Eve)], and from them both He created many men and women; and fear Allâh through Whom you demand (your mutual rights), and (do not cut the relations of) the wombs (kinship). Surely, Allâh is Ever an All¬Watcher over you

An-Nisa 1

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

Don't befriend disbelievers

Let not the believers take the disbelievers as Auliyâ (supporters, helpers) instead of the believers, and whoever does that will never be helped by Allâh in any way, except if you indeed fear a danger from them. And Allâh warns you against Himself (His Punishment)[], and to Allâh is the final return.

Clarificaion
It is mentioned in Tafsir Al Jalalaeyen that this order was for the days before the hegemony of Islam and the order applies to every place where the Muslims are in minority in a land where unbelievers are in majority.

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

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).
