And just for the sake of argument, I don’t think anyone can sense the aura of properly veiled Muslim woman. Her clothing would be too loose to offer any info on that matter! –unless you are talking at the nano level.

Also we at our Masjid have a wall and do not mix male and female. however we have a camera hooked up into the main area with TV for the women to watch what is going on if you want to use that excuse for not having a wall. Also the nabi sallahu ahlihim to my understanding did not stand straight in front of women when he would talk to them in jamma he would turn half way as to not look directly at them if this is right and true then that is where your heart should be if I am wrong i ask you to forgive me and correct me so i don’t repeat this if it is an error

and Allah the most high knows best

I am sorry i don’t have the exact detail for my understanding the only thing i have is to listen to Ahmed Ali this strong human and listen to his work this is where i got the info from and i love Ahmed Ali for the sake of Allah and for the knowledge he passed on to inshAllah khair may Allah forgive you and make dua for me inshAllah

Anyone who has taken a speech class – scratch that, anyone who has ever talked to another human being knows that not all aspects of communication are verbal. When we talk, we may or may not make facial gestures, hand motions, and other physical movements to help get our point across. In fact, studies show that 70% of communication is rooted in something called paralanguage, an auxiliary form of communication that includes everything except speech. In this specific example, the aspect of paralanguage that’s most important is called kinesics, more commonly referred to as body language. In layman’s terms, the motions a speaker makes during his speech directly improves or worsens the delivery of his message.

The Quran commands both genders to lower their gazes. So I think it can be safely implied that we aren't supposed to sit around and analyze the opposite gender's body language in order to accurately understand what he or she is trying to communicate. Have you heard the hadith about the first glace being forgiven…and voluntary subsequent gazes being disallowed? If yes, then how can it be said that paying attention to a speaker's body language is all right and essential?

And seriously, from a Muslim woman's perspective do you think the haya-ful females of the Muslim Ummah would feel comfortable with the possibility that the movements of their bodies are being analyzed by the Muslims brothers while they are talking? That would be a really creepy situation to be in, to say the least.

Also, please remember that Allah has effectively communicated to us through the Quran and the Quran in its current 'primary' form is a textual document (there is no audio or video to it). I don't think most of us feel the need to look at Allah or even the Prophet (sa) in order to accurately understand what the Holy book is saying.

Finally, whenever religious matters are discussed the points that are being argued for should be backed up by evidence from the Quran and the Sunnah as these sources of evidence supersede any sort of para-lingual (or any other kind of human discovered) “evidence”.

Siraj, I think, has the best response to this question about the barrier. The last one that he wrote.

The things which I said were at the beginning of the post so those are between you ie. the readers and me. However, the hadith themselves are intended for the sake of knowledge and amal or actions/implementations of that knowledge. There they[hadith] are written in truth.

Narrated Anas (Allah be pleased with him): The fact which stops me from narrating a great number of Hadiths to you is that the Prophet (peace be upon him) said: “Whoever tells a lie against me intentionally, then (surely) let him occupy his seat in Hell-fire.
(Sahih Al-Bukhari Vol 1).

No judge must give judgement between two people when he is angry.
(Bukhari, Muslim).

The man who is most hateful to God is the one who quarrels and disputes most. (Bukhari, Muslim).

Do you know the thing which most commonly brings people into paradise? It is fear to God and good character. Do you know what most commonly brings people to hell? It is the hollow things; the mouth and the private parts.
(Tirmidhi, Ibn Majah).

Coarse talk does not come into anything without disgracing it, and modesty does not come into anything without adorning it.
(Tirmidhi).

If you guarantee me six things on your part, I shall guarantee you paradise: speak the truth when you talk, keep a promise when you make it, when you are trusted with something fulfil your trust, avoid sexual immorality, lower your eyes and restrain your hand from injustice.
(Baihaqi).

Avoid envy, for envy devours good deeds just as fire devours fuel.
(Abu Dawud).

“Believers are to one another like a building whose parts support one other.” He then interlaced his fingers.
(Bukhari, Muslim).

That which is lawful is plain and that which is unlawful is plain and between the two if them are doubtful matters about which not many people know. Thus he who avoids doubtful matters clears himself in regard to his religion and his honour, but he who falls into doubtful matters falls into that which is unlawful, like the shepherd who pastures around the sanctuary, all but grazing therein. Truly every king has a sanctuary, and truly Allah’s sanctuary is His prohibitions. Truly in the body there is a morsel of flesh which, if diseased, all of it is diseased. Truly it is the heart.
(Bukhari, Muslim).

What I have forbidden to you, avoid; what I have ordered you [to do], do as much of it as you can. It was only their excessive questioning and their disagreeing with their Prophets that destroyed those who were before you.
(Bukhari, Muslim).

Allah the Almighty has laid down religious duties, so do not neglect them; He has set boundaries, so do not overstep them; He has prohibited some things, so do not violate them; about some things He was silent out of compassion for you, not forgetfulness, so seek not after them.
(Daraqutni)

Narrated Abdullah bin Amr bin Al As (Allah be pleased with him): I heard Allah’s Apostle (peace be upon him) saying: “Allah does not take away the knowledge by taking it away from (the hearts of) the people, but takes it away by the death of the religious learned men till when none of the (religious learned men) remains, people will take as their leaders ignorant persons who when consulted will give their verdict without knowledge. So they will go astray and will lead people astray.” (Sahih Al-Bukhari Vol 1).

Ibn Masud reported the Messenger of Allah as saying: “A woman is an object of concealment for when she goes out the devil presents her in alluring looks before men.”
(Tirmidhi).

A time will come to mankind when man will not care whether what he gets comes from a lawful or an unlawful source.
(Bukhari).

Do not ask for any high office, for if you are given it after asking, you will be left to discharge it yourself; if you are given it without asking you will be helped to discharge it.
(Bukhari, Muslim).

Woe to him who tells things, speaking falsely, to make people laugh thereby! Woe to him! Woe to him!
(Ahmad, Tirmidhi, Abu Dawud, Darimi).

Sufyan bin Abdullah ath Thaqafi told when he asked God’s messenger what he feared most for him, he took hold of his tongue and said, “This.”
(Tirmidhi).

Some claim that a barrier is biddah. Correct me if I am wrong but we should follow the sunna of the prophet and the one after him (companions). Especially the four khalifas after the prophet (SAWS). And didnt Umar (RA) forbid women from coming to the mosque. And when the ladies complained to Ayesha (RA) she said that this action was in the bounds of the sharia and not biddah. So the pardah is more or less like the action of Umar. I may be wrong correct me with hikmah if I am.

But brother Siraj tore it up nonetheless.

JazakaAllah khair for the great advice, bro. I always find your posts full of wisdom and lessons.
