Hijab According to Quran

Quraan tells us there is ZERO Tolerance for negative thinking and it comes into boundary limits:
Say: "Come, I will recite unto you what Allah has (really) prohibited you from": Join not anything as equal with Him; be good to your parents; kill not your children for (fear of) poverty;- We provide sustenance for you and for them;- come not near to shameful deeds(acts). Whether open or secret; take not life, which Allah hath made sacred, except by way of justice and law: this He has command you, that you may learn wisdom. (Al_Quraan_006:151)
Nor come near to adultery: for it is a shameful (deed) and an evil, opening the road (to other evils). (Al_Quraan_017:032)
But he who seeks to go beyond this (legal wife or captives from war), these it is that go beyond the limits. (Al_Quraan_017:032)

Quraan tells us to lower our gaze:
"Say to the believing men that they should lower their gaze and guard their modesty......And say to the believing women that they should lower their gaze and guard their modesty; that they should not display their beauty and ornaments except what ordinarily appear thereof; that they should draw their veils over their bosoms...." (Al_Quraan_024:030-031)

Quraan is the only Holy Book which suggests you to Marry only one:
And if you fear that you cannot act equitably towards orphans, then marry such women as seem good to you, two and three and four; but if you fear that you will not do justice (between them), then (marry) ONLY ONE or what your right hands possess; this is more proper, that you may not deviate from the right course. (Al_Quraan_004:003)

Quraan tells us to Bequest in favour of your wives of maintenance for a year (minimum) unless they themselves go away:
And those of you who die and leave wives behind, (make) a bequest in favor of their wives of maintenance for a year (minimum) without turning (them) out, then if they themselves go away, there is no blame on you for what they do of lawful deeds by themselves, and Allah is Mighty, Wise. (Al_Quraan_002:240)

Quraan tells us that Momin and Mominah are Protecting Friends of each other:
And (as for) the believing men and the believing women, they are guardians of each other; they enjoin good and forbid evil and keep up prayer and pay the poor-rate, and obey Allah and His Messenger; (as for) these, Allah will show mercy to them; surely Allah is Mighty, Wise. (Al_Quraan_009:071)

Are our cousins worse than our slaves (war captives)? We are commanded to help righteous slaves financially and help them to get married as well:
And marry those among you who are single and those who are fit among your male slaves and your female slaves; if they are needy, Allah will make them free from want out of His grace; and Allah is Ample-giving, Knowing. And let those who do not find the means to marry keep chaste until Allah makes them free from want out of His grace. And (as for) those who ask for a writing from among those whom your right hands possess, give them the writing if you know any good in them, and give them of the wealth of Allah which He has given you; and do not compel your slave girls (war captives) for sex, when they desire to keep chaste, in order to seek the frail good of this world's life; and whoever compels them, then surely after their compulsion Allah is Forgiving, Merciful. (Al_Quraan_024.032-033)

Are our cousins worse than our slaves (war captives)? Do not turn your home into a torture cell for your cousins:
Say to the believing men that they should lower their gaze and guard their modesty: that will make for greater purity for them: And Allah is well acquainted with all that they do. And say to the believing women that they should lower their gaze and guard their modesty; that they should not display their beauty and ornaments except what (must ordinarily) appear thereof; that they should draw their veils over their bosoms and not display their beauty except to their husbands, their fathers, their husband's fathers, their sons, their husbands' sons, their brothers or their brothers' sons, or their sisters' sons, or their women, or their slaves (war captives) whom their right hands possess, or male servants free of physical needs, or small children who have no sense of the shame of sex; and that they should not strike their feet in order to draw attention to their hidden ornaments. And O ye Believers! turn ye all together towards Allah, that ye may attain Bliss. (Al_Quraan_024.030-031)

Nephews and nieces are allowed to come at our home:
There is no blame on the blind man, nor is there blame on the lame, nor is there blame on the sick, nor on yourselves that you eat from your houses, or your fathers' houses or your mothers' houses, or your brothers' houses, or your sisters' houses, or your paternal uncles' houses, or your paternal aunts' houses, or your maternal uncles' houses, or your maternal aunts' houses, or what you possess the keys of, or your friends' (houses). It is no sin in you that you eat together (including JOINTFAMILY-SYSTEM which may help saving lots of expenditures) or separately. So when you enter houses, greet your people with a salutation from Allah, blessed (and) goodly; thus does Allah make clear to you the communications that you may understand. (Al_Quraan_024:061)

Hijaab of the sound of Jewelry:
And say to the believing women that they cast down their looks and guard their private parts and do not display their ornaments except what appears thereof, and let them wear their head-coverings over their bosoms, and not display their ornaments except to their husbands or their fathers, or the fathers of their husbands, or their sons, or the sons of their husbands, or their brothers, or their brothers' sons, or their sisters' sons, or their women, or those whom their right hands possess, or the male servants not having need (of women), or the children who have not attained knowledge of what is hidden of women; and let them not strike their feet so that what they hide of their ornaments may be known; and turn to Allah all of you, O believers! so that you may be successful. (Al_Quraan_024.031)

Hijaab of the sound of Voice:
O wives of the Prophet! you are not like any other of the women; If you will be on your guard, then be not soft in (your) speech, lest he in whose heart is a disease yearn; and speak a good word.
(Al_Quraan_033.032)
