What is Haya?
Haya itself is derived from the word hayat which means life. This term covers a wide number of concepts. In English, it may be translated as modesty, shyness, self-respect, bashfulness, shame, honour, humility, etc. It’s like an ornament of which beatifies a girl, a piece of jewel that no money can buy, no shop can stock and no tailor can stitch, it’s taught, passed down, learned and practised, it’s an art form which is mastered through Islam, of one of the basic needs which a woman should possess, to be a modest Muslimah:
Narrated by Abu Huraira (ra The Prophet said,;saw2: “Faith (Belief) consists of more than sixty branches (i.e. parts). And Haya is a part of faith.” (Bukhari)
Modesty is part of our character, a part of our faith, something we should be proud to have attained:
Narrated Abdullah ibn Umar (ra The Prophet:saw2: (saws) passed by a man who was admonishing his brother regarding Haya and was saying, “You are very shy, and I am afraid that might harm you.” On that, Allah’s Apostle said, “Leave him, for Haya is (a part) of Faith.” (Bukhari)
Now the above hadith is also a form of proof that “shyness” is not just something regarding women but also an attribute that believing men should have, for it is an indication if their fear of Allah and an indication of the value of their Deen, but my thread is emphasising on the girls, the women of today.
There are two forms of Haya, inner and outer good or bad;
Inner:
Speech
Actions
Langauge
Mind
Outer:
Dress Code
Walk
Gaze
The good Hayâ’ is to be ashamed to commit a sin or a thing which Allah and His Messenger :saw: has forbidden, and bad Hayâ’ is to feel ashamed to do a thing, which Allah and His Messenger 
ordered to do.
Firstly, to talk about the types of Good haya. For example, anyone who is a believer, he/she should build their personalities and their character with the good dimensions of haya. The most important is that he/she must be shy of doing ANYTHING displeasing to Allah (swt), with the belief that he/she will have to answer for all their deeds. If one develops a sense such as this one, it will help the believer to obey all of Allah's command and to stay away from sins. Once the believer realises that Allah (swt) is watching us all the time and we will have to answer to every move we make in this dunya (world), he/she would not neglect any order from Allah or His Messenger (saws). So the stronger this sense of haya becomes, the more it motivates one to make sure that Allah (swt) doesn't see him/her doing anything prohibited. The way to develop this haya is that one must keep learning and absorbing more knowledge and applying it to their lives.
Another type of haya is more of a social aspect concerning others besides Allah (swt). Normally these things often come in regard with ones relationship with family. For instance, a child not wanting to do something displeasing to his mother, or a wife not wanting to do something displeasing to her husband or even a student who is careful about saying something incorrect in front of his teacher.. Last but not least is the type of haya in which the believers become shy of themselves. This is when they have reached the peek of their Iman. What this means is that if they do, or say, or see, anything wrong or even commit the tiniest sin, they start to feel extremely bad and embarrassed or they feel extreme guilt in their heart. This builds a high degree of self-consciousness and that is what strengthens the believers commitment to Allah (swt).
Haya and Iman are interdependent; therefore either they both exist together or they both perish. Thus, the Prophet (saws) has said in one hadith,* “When there is no haya left, then do as you please.” *
*Abdullah ibn Umar (ra) narrated that the Prophet:saw2: (saw) said: “Indeed haya (modesty) and Iman are Companions. When one of them is lifted, the other leaves as well.” (Baihaqi)
*
Modesty (haya) and maintaining one’s honour and dignity are of primary importance in preserving the moral fibre of any society. This is why modesty has been called the ornament of a woman, which protects her from many sins and which prevents ill-intentioned men from daring to have bad thoughts about her. This haya has been made a part of her nature to safeguard her from being abused by immoral men.
Narrated on the authority of Anas bin Malik, the Prophet:saw2: (saw) said: When lewdness is a part of anything, it becomes defective; and when haya is a part of anything it becomes beautiful. (Tirmidhi)
Today vulgarity and all its ingredients have become a common place even among well-known Muslims in the zeal of imitating the disbelievers. It is these people who have been struggling to bring Muslim women out of Hijab into immodesty and indecency. They have adopted the lifestyles of the disbelievers more than the traditions of the Prophet (saws). Such people are in a dilemma. On the one hand, they desire to freely look at the half-clad bodies of their wives and daughters of other Muslims on the streets; and on the other hand, they do not have the courage to deny the teachings of the Holy Qur'an and the Prophet (saws). Indulging in indecency for so long has killed the sense of modesty (haya) which Islam had commanded them to preserve.
*The Prophet:saw2: (saws) said: “Haya and Trustworthiness will be the first to go from this world; therefore keep asking Allah for them.” (Baihaqi)
*
In conclusion, the Muslim community has implemented the modest attire for a Muslimah but have bypassed the mannerisms to go with it, their speech vulgar and infused with foul words and brimming with sexual innuendo. The social media generation has exploded, obliterating the ounce of decency left in the Muslim society, now shamelessness has reached a all new height, in front of family members, who ‘like’ such actions, and even the surprised gasp has disappeared.
If the core of the subject is analysed there is a deeper issue of lack of self worth, lack of self respect to throw yourself into the path of a strange man and lure him into sinful activities, to make yourself look and feel better if another is enjoying the carnal nature of your beauty,
So value your decency, your modesty, your manners, it’s what beautifies a woman, it’s one of the core necessities of a girl to make her a lady. Do not indulge in vain or immoral talk, do not inject foul words to make yourself more acceptable to the modern society, if they do not appreciate your decency, then it is them at fault and you need to find new friends who do appreciate the value of modesty, decency, and good manners. Change your friends, not your good habits, because bad friends, can become bad habits and can lead to destruction of the soul.
**“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…….” (Qur’an: Surah Nur, 30-31)
** Malik b Uhaimir reported that he heard the Prophet :saw: saying that, “Allah (swt) will not accept any good deeds or worship of an immodest and vulgar person.” We asked “Who is a vulgar and immodest person?” He replied, “A man who’s wife entertains Ghair-mehram men.”
for your contribution. ‘**Haya’ **in urdu means ‘modesty’ and ‘Hayat’ in arabic means ‘life’. As far I understand ‘Haya’ doesn’t mean ‘life’ nor its arabic word. If you refer in first line ‘Haya’ as ‘life’ and in second line as ‘modesty’ than it will lil bit make confusion to one who read the hadith and get stuck at word ‘haya’ either its about ‘life’ or ‘modesty’.
