1. An act of obedience.
The hijab is an act of obedience to Allah and to his prophet (pbuh), Allah says in the Qur'an: `It is not for a believer, man or woman, when Allah and His messenger have decreed a matter that they should have an option in their decision. And whoever disobeys Allah and His Messenger, has indeed strayed in a plain error.' (S33:36).
Allah also said: 'And tell the believing women to lower their gaze (from looking at forbidden things) and protect their private parts (from illegal sexual acts, etc) and not to show off their adornment except what must (ordinarily) appear thereof, that they should draw their veils over their Juyubihinna.'(S24:31).
Juyubihinna: The respected scholars from As-Salaf As-Saleh (righteous predecessors) differed whether the veil cover of the body must include the hands and face or not. Today, respected scholars say that the hands and face must be covered. Other respected scholars say it is preferable for women to cover their whole bodies.
2. The Hijab is IFFAH (Modesty).
Allah (subhana wa'atala) made the adherence to the hijab a manifestation for chastity and modesty. Allah says: 'O Prophet! Tell your wives and your daughters and the women of the believers to draw their cloaks (veils) over their bodies (when outdoors). That is most convenient that they should be known and not molested.' (S33:59). In the above Ayaah there is an evidence that the recognition of the apparent beauty of the woman is harmful to her. When the cause of attraction ends, the restriction is removed. This is illustrated in the case of elderly women who may have lost every aspect of attraction. Allah (swt) made it permissible for them to lay aside their outer garments and expose their faces and hands reminding, however, that is still better for them to keep their modesty.
3. The hijab is Tahara (Purity)
Allah (swt) had shown us the hikma (wisdom) behind the legislation of the hijab: `And when you ask them (the Prophet's wives) for anything you want, ask them from behind a screen, that is purer for your hearts and their hearts.' (S33:53).
The hijab makes for greater purity for the hearts of believing men and women because it screens against the desire of the heart. Without the hijab, the heart may or may not desire. That is why the heart is more pure when the sight is blocked (by hijab) and thus the prevention of fitna (evil actions is very much manifested. The hijab cuts off the ill thoughts and the greed of the sick hearts:
`Be not soft in speech, lest he in whose heart is a disease (of hypocrisy or evil desire for adultery, etc) should be moved with desire, but speak in an honorable manner.' (S33:32)
4. The hijab is a Shield
The prophet (pbuh) said: "Allah, Most High, is Heaven, is Ha'yeii (Bashful), Sit'teer (Shielder). He loves Haya' (Bashfulness) and Sitr (Shielding; Covering)." The Prophet (pbuh) also said: "Any woman who takes off her clothes in other than her husband's house (to show off for unlawful purposes), has broken Allah's shield upon her. " The hadith demonstrates that depending upon the kind of action committed there will be either reward (if good) or punishment (if bad).
5. The hijab is Taqwah (Righteousness)
Allah (swt) says in the Qur'an: `O children of Adam! We have bestowed raiment upon you to cover yourselves (screen your private parts, etc) and as an adornment. But the raiment of righteousness, that is better.'(S7:26). The widespread forms of dresses in the world today are mostly for show off and hardly taken as a cover and shield of the woman's body. To the believing women, however the purpose is to safeguard their bodies and cover their private parts as a manifestation of the order of Allah. It is an act of Taqwah (righteousness).
6. The hijab is Eemaan (Belief or Faith)
Allah (swt) did not address His words about the hijab except to the believing women, Al-Mo'minat. In many cases in the Qur'an Allah refers to the "the believing women". Aisha (RA), the wife of the prophet (pbuh), addressed some women from the tribe of Banu Tameem who came to visit her and had light clothes on them, they were improperly dressed: "If indeed you are believing women, then truly this is not the dress of the believing women, and if you are not believing women, then enjoy it."
7. The hijab is Haya' (Bashfulness)
There are two authentic hadith which state: "Each religion has a morality and the morality of Islam is haya'" AND "Bashfulness is from belief, and belief is in Al-Jannah (paradise)". The hijab fits the natural bashfulness which is a part of the nature of women.
8. The hijab is Gheerah
The hijab fits the natural feeling of Gheerah, which is intrinsic in the straight man who does not like people to look at his wife or daughters. Gheerah is a driving emotion that drives the straight man to safeguard women who are related to him from strangers. The straight MUSLIM man has Gheerah for ALL MUSLIM women In response to lust and desire, men look (with desire) at other women while they do not mind that other men do the same to their wives or daughters. The mixing of sexes and absence of hijab destroys the Gheera in men. Islam considers Gheerah an integral part of faith. The dignity of the wife or daughter or any other Muslim woman must be highly respected and defended.
Verses that have to do with hijab:
1 Allaah says (interpretation of the meaning):
And tell the believing women to lower their gaze (from looking at forbidden things), and protect their private parts (from illegal sexual acts) and not to show off their adornment except only that which is apparent (like both eyes for necessity to see the way, or outer palms of hands or one eye or dress like veil, gloves, headcover, apron), and to draw their veils all over Juyoobihinna (i.e. their bodies, faces, necks and bosoms) and not to reveal their adornment except to their husbands, or their fathers, or their husband's fathers, or their sons, or their husband's sons, or their brothers or their brother's sons, or their sister's sons, or their (Muslim) women (i.e. their sisters in Islam), or the (female) slaves whom their right hands possess, or old male servants who lack vigour, or small children who have no sense of feminine sex. And let them not stamp their feet so as to reveal what they hide of their adornment. And all of you beg Allaah to forgive you all, O believers, that you may be successful
[al-Noor 24:31]
2 Allaah says (interpretation of the meaning):
And as for women past childbearing who do not expect wedlock, it is no sin on them if they discard their (outer) clothing in such a way as not to show their adornment. But to refrain (i.e. not to discard their outer clothing) is better for them. And Allaah is Allâh ‘Hearer, Allâh ‘Knower [al-Noor 24:60]
Women past childbearing are those who no longer menstruate, so they can no longer get pregnant or bear children. We shall see below the words of Hafsah bint Sireen and the way in which she interpreted this verse.
3 Allaah says (interpretation of the meaning):
O Prophet! Tell your wives and your daughters and the women of the believers to draw their cloaks (veils) all over their bodies (i.e. screen themselves completely except the eyes or one eye to see the way). That will be better, that they should be known (as free respectable women) so as not to be annoyed. And Allaah is Ever Oftâh‘Forgiving, Most Merciful [al-Ahzaab 33:59]
4 Allaah says (interpretation of the meaning):
O you who believe! Enter not the Prophet's houses, unless permission is given to you for a meal, (and then) not (so early as) to wait for its preparation. But when you are invited, enter, and when you have taken your meal, disperse without sitting for a talk. Verily, such (behaviour) annoys the Prophet, and he is shy of (asking) you (to go); but Allaah is not shy of (telling you) the truth. And when you ask (his wives) for anything you want, ask them from behind a screen, that is purer for your hearts and for their hearts. And it is not (right) for you that you should annoy Allaah's Messenger, nor that you should ever marry his wives after him (his death). Verily, with Allaah that shall be an enormity [al-Ahzaab 33:53]
