In your situation, you need to think about what is right and wrong, even if it means breaking contact with your brother and sister-in-law. First of all, you should know that an intimate/sexual relationship with your brother-in-law is not allowed in Islam. It is a sin that you must repent of. However, I am glad to hear that you realized that what you did with your brother-in-law was a great sin. « Al Hamuw: the husband`s brother. He (i.e. this hadith) means: his entry (to his brother`s wife) in the absence of his brother. The Prophet (peace and blessings of Allah be upon him) clarified that he is the heaviest of all dangers, which is why he said: « The brother-in-law is death », because the ajnabee (stranger) does not dare to enter, and when he enters, he finds caution. As for the man`s brother, he enters his brother`s house and there is no worry, so there is something similar to death. That is why the Prophet (peace and prayers be upon him) clearly tells us in this hadith that it is up to the man (i.e. the brother-in-law) to be careful towards the wife (the brother`s wife), and also towards the woman (beware of his brother-in-law). [12] In Islaam, the `Dhu Mahaarim (chant: Mahram)` are clearly defined; A mahram is the husband of a woman or man with whom this woman cannot marry at all according to Israeli jurisprudence. This may be due to consanguinity (such as father, son, brother, paternal uncle, etc.) or a foster family.

For no other non-Mahram has the Prophet (peace and blessings of Allah be upon him) has used such a clear and categorical formulation of caution as for the brother-in-law. Even though our culture and traditions allow a sister-in-law to be openly mixed with her brother-in-law as if he were her real brother, the Hamuw is not considered a blood brother or a blood brother in Sharia (Islamic law). Therefore, the addition of « brother-in-law » in « brother-in-law » does not refer to Islamic law. In Arabic, « hamuw » means « the brother of the husband or his relatives; For example, the son of his paternal uncle or the son of his maternal uncle. [4] It may also be the sister`s husband. [5] Let us briefly summarize again. In summary, a person`s wife must observe the full hijab in front of her brother-in-law, and she must not be alone with him. One of the signs of floral life and well-being is the beautiful fragrance that emanates from it; Similarly, the modesty emanating from the Muslim woman is a sign of the life of her eeman (faith). Wholeheartedly mingling with the brother-in-law can weaken modesty, which is worrying since the Prophet [(peace and prayers be upon him) said: « .. Modesty is a branch of faith.

(Saheeh Muslim, Book 1, Hadith 56) Of course, you should never do that. But telling your brother-in-law that you will tell everyone, you will scare him and drive him away from you. From the words of the Prophet (peace and blessings of God be upon him), we can clearly see that men should not have open dominion to enter women as they wish and when they wish. On the contrary, there must be a necessary and urgent restriction and division among non-mahrams. Let us remember that the Prophet (peace and blessings of Allah be upon him) was mentioned first in the hadith concerning the brother-in-law: such an attitude is also death for one`s own shame, since one does not respect one`s sister`s privacy. If a sister cannot be trusted in such a private and intimate matter, what is left of her? We have already issued fatwa 84608, which states that the woman has the right to have a shelter with separate amenities and that she is not obliged to live with her in-laws in the same house, which is not separated. On the contrary, non-mahrams are not allowed to live with her, like the husband`s brother. `Uqbah ibn `Aamer reported that the Prophet said, « Beware of contracting marriageable women. » An Ansaar man remarked: « O! Messenger of Allah, what do you say about the male son-in-law (the male relative of the woman`s husband like her brother, uncle, cousin, etc.)? He replied, « He is death itself (that is, His isolation from it is as grave and dangerous as death). [Al-Bukhari and Muslim] Believing women of the past, even behind their veils, exercised extreme caution when speaking to a non-Mahram when applying the words of Allah (`azza wa jall): if you keep your duty (to Allah), do not speak softly, lest the one in whose heart there is sickness be moved by desire, but speak in an honorable manner.

(Surat al-Ahzaab [30]:30-33) They hastened to obey their Lord`s command, and therefore, if they walked and spoke, they would walk in a way that embodied righteousness and modesty. In fact, there is a big difference between them and many women today who walk seductively and speak complacently in front of and with their non-mahrams. Such women often come to testify and face the harmful consequences of disobedience to the command of Allah and His Rasool (peace be upon him) in this life before the next. Therefore, it is haram for a person to give his brother the chance to be alone with his wife. Some people take this issue lightly; You will find him (the husband) with his wife and he has a brother who has reached puberty age and he (the husband) goes to work leaving his wife and brother alone in the house. This is haram (forbidden), for Satan flows into the son of Adam like the flow of blood. Moreover, the Prophet (peace and blessings of Allaah be upon him) warned us against gender isolation in similar relationships: He said, « In-laws are like death! » In other words, they are at greater risk of falling into sin than strangers because they are more likely to meet and interact, and the result would be much more catastrophic than death.
