A mahram is an unmarriageable kin with whom marriage or sexual intercourse would be considered haram, illegal in Islam, or people from whom hijab is not obligatory.
Talking with non Mahram must be limited to necessary talk only. It must never contain any word which can cause or initiate feelings. In fact, there is no question of friendship between you and your non Mahram. Friendship can involve sharing secrets and confidential matters, which can not be with a non Mahram.
It is not permissible to touch non Mahram. You must do your best to avoid that, even by changing the vehicle.
If you know that this non-mahram man will look at your images without hijab, then no it is not permissible for you to give them to him to get them developed. Your choice is to either print the images yourself, using the available printing machines in certain stores, or go to a place run by a female, or other similar options.
And Allah knows best.
If listening to non Mahram women does not cause mirth, bad thoughts or bad desires, then it is permissible for men to listen to them. It becomes unlawful when it causes mirth, bad thoughts or bad desires.
Your wife has misunderstood the Islamic rule in this matter. Mahram is the person who is permanently forbidden for marriage with her under any circumstance for life e.g. her real brother , real uncle, real father, father in law, her son and son in law. Her sister's husband is not permanently forbidden to marry her, but only when her sister is his wife. If she dies, God forbid, or if she is divorced from him, marriage will be then allowed between this man and any of the unmarried sisters of his ex-wife.
Her sister's husband is not Mahram at all and must observe full Hijab in front of him like any other non Mahram man.
It is very important for your respected wife to educate herself about the definition and rulings related to maḥram/non-maḥram cases.
Unfortunately she is misinformed, and has only half of the facts correct.
In Islam, a man cannot marry two sisters at one time, but this does not mean that the wife's sister becomes maḥram to the husband, nor does it mean that the sister's husband becomes maḥram to the wife's sister.
So, although he cannot marry his sister's wife as long as he is married to his wife, it still does not mean that she becomes maḥram to him.
It is still haram for him to see her without hijab, or look at her with lust, or shake her hand, or be alone with her, and so on.
This is a view that all our jurists have.
As for the case of her staying at their home, if all other shar'i matters are observed, yes she can.
And Allah knows best.
This is an interesting question, and it can be tackled from different angles.
In general, the ruling is that a female (mahram or non-mahram) cannot pray beside or in front of a male. This is not purely a matter of preventing men from unlawful glancing, because if that was the case, then a wife could pray in front of a husband.
Islam focuses on elevating the status of a women beyond her being sexualised by others, and even by herself. This can be seen not only in mandating hijab, but even in the obligatory or recommended (mustahab) acts in prayer, like how she prostrates, and how she stands back up.
This is all for the purpose of preserving her modesty, and also to eliminate any likelihood of a lustful gaze (haram or halal), during prayer in particular, for the purpose of gaining that absolute concentration in prayer.
Of course, we are assuming that this is just one of the reasons behind the ruling. It's similar to the story of Prophet Moses (a.s.) and the daughters of Prophet Shu'ayb (a.s.). However, the reality is that like many other rulings, we do not have the precise reason for it. There could certainly be more reasons.We are just assuming that it is a matter of convenience and a spiritual matter for concentration, but it could be more than that.
The main issue is in prayer we need to attain ḥudhūr al-qalb, which is presence of the heart.We need to be concentrating completely on our prayer, and remove anything that would distract us.
We understand that it is also the very natural structure of the female that Almighty God has created with her beauty and attraction that could contribute to a male (her mahram or non-mahram) being distracting and glancing at her.
Please look at all the other rulings for prayer, which can also hint to how important it is to avoid loss of concentration, like praying in front of an image, etc.
It could also be for convenience, so a woman does not feel embarrassed or exposed when she is bending down for ruku' or sujud.
And so on.
Furthermore, please refer to your Marja' taqleed on this ruling, because there are some jurists who consider it mustahab, and not wajib.
And Allah knows best.
Yes. Grand mother of the wife is Mahram just like her real mother.
It depends on the age and situation of you and the Mahram member of your family. It is not obligatory to cover your arms and legs in from of an old Mahram being sure that uncovering arms and legs will never cause nor initiate unwanted feeling. In general, it is not obligatory to cover in front of Mahram, that parts of your body which are usually uncovered at home with your family, provided that it should not cause bad feeling of desire or shame.
As a female, it took some time for me to realise that it is not unusual for men to feel some physical attraction when they look at women in their immediate family (even a daughter or sister), especially if they are significantly uncovered. Also, that many men do subconsciously "track" the attractiveness of female relatives (even if they themselves would never act on it and would deny it, but still they may be subconsciously evaluating how attractive they may come across to other men).
Of course given the taboo of incest these thoughts are usually shoved aside. However, sometimes they come out, for instance, some men become uncomfortable when their daughters pass puberty and develop a womanly figure. Or sometimes in sharp comments about clothing and behaviour, etc.
I say "as a female" because I don't think most women tend to feel the same way about male relatives, and the majority of women would probably respond with something along the lines of "Ewwwww".
[An exception would be with respect to blood relatives who never met in childhood, for instance, a half brother and half sister who meet each other only in adulthood. There is some psychological phenomenon that happens whereby it is not uncommon to feel some sort of attraction, in which case that could also be taken into consideration here, even though technically they are mahram and certainly a marriage is unlawful.]
I am not saying that this always happens, but just that it isn't an unusual dynamic and is one that it took me time to put into words. So it could be considered, at the end of this day, this comment either will apply or won't apply to a person's family dynamic.
(Also I apologise for any generalisations in the above, generalistions happen but I do acknowledge the perils of them!)
Yes, the obligatory dress in front of Mahram like real father, brother, real uncles must cover the parts of the body which if left uncovered can cause bad feelings or bad effect. Although full Hijab is not obligatory in front of Mahram close relatives ( mentioned above) but modest dress is obligatory.
Yes. Your mother's or father's maternal or paternal direct uncles are Mahram for you just like any of your direct uncles.
