Modesty And Flirting

Facts About Modesty
Modesty may be expressed in social interaction by communicating in a way exhibiting humility, shyness, or simplicity. The general elements of modesty include:

• Downplaying one's accomplishments Modesty
• Behavior, manner, or appearance intended to avoid impropriety or indecency
• Avoiding insincere self-abasement through false or sham modesty, which is a form of boasting. 

A second expression of modesty, isolated from communication and human interface, focuses more on internal perception of superiority and may be expressed in the following ways:

• through work ethic,
• motivation for self improvement,
• and tolerance of others.

Facts About Flirting:
Flirting is a playful, romantic or sexual overture by one person to another subtly indicating an interest in a deeper relationship with the other person, and can involve verbal communication as well as body language.
 

Body language can include flicking the hair, eye contact, brief touching, open stances, proximity etc. Verbal communication of interest can include the vocal tone, such as pace, volume, intonation. Challenges (teasing, questions, qualifying, feigned disinterest) serve to increase tension, test intention and congruity.
Flirting usually involves speaking and behaving in a way that suggests a mildly greater intimacy than the actual relationship between the parties would justify, though within the rules of social etiquette, which generally disapproves of a direct expression of sexual interest. This may be accomplished by communicating a sense of playfulness or irony. Double entendres, with one meaning more formally appropriate and another more suggestive, may be used.

What Quran says:
And do not go near extramarital sex. Indeed, it is an immorality and an evil way. [Quran, 17:32]

Have you seen the one who takes as his god his own desire? Then would you be responsible for him? [Quran, 25:43]

O children of Adam, We have bestowed upon you clothing to cover your shame and as adornment. But the clothing of righteousness - that is best. That is from the signs of God that perhaps they will remember. [Quran, 7:26]

"Say to the believing men they should lower their gaze and they should guard their chastity. That is purer for them. Indeed God is All-Aware of what they do." [Quran, 24:30]

And say to the believing woman that they should lower their gaze and that they should guard their chastity, and not display their adornment except what is apparent of it. And let them cast their clothes over their cleavage. Let them not show off their attraction except to their husbands, or their fathers, or fathers of their husbands, or their sons, or the sons of their husbands, or their brothers, or the sons of their brothers, or the sons of their sisters, or their children that come after them, or those who are still their dependents, or the male servants who are without need, or the child who has not yet understood the nakedness of women. Let them not strike with their feet in a manner that reveals what they are keeping hidden of their attraction. And repent to God, all of you believers, that you may succeed. [Quran, 24:31]

Indeed, those who have put into fatanoo the believing men and believing women and then have not repented will have the punishment of Hell, and they will have the punishment of the Burning Fire. [Quran, 85:10]

The Arabic words fatanoo (فتنوا) is derived from the root word fitnah (فتنة), which literally means temptation, or putting someone to the test.

Conclusion:
O you who believe, do not follow the footsteps of Satan. And whoever follows the footsteps of Satan - indeed, he enjoins immorality and wrongdoing. And if not for the favor of God upon you and His mercy, not one of you would have been pure, ever, but God purifies whom He wills, and God is Hearing and Knowing. [Quran, 24:25]
