A brother is a man or boy who shares one or more parents with another. Although the term typically refers to a familial relationship, it is sometimes used endearingly to refer to non-familial relationships. A full brother is a first degree relative.
From a shar'i perspective, the husband's brother or any other person can live in a house, together, as long as: 1. the couple have their privacy, and there is no intrusion, 2. there is no khalwah, which means only the wife and the brother-in-law are home alone, and 3. the females in the house observe correct hijab in the presence of the non-mahram men, which in this case would be the husband's brother.
Now, we have to ask whether this is something the wife is comfortable with. Is she comfortable with the accommodation arrangement? Does she have her privacy? Is she able to be as she wants in the house, and is the brother in law's presence affecting their relationship?
A wife wants to feel secure in her house, and also feel comfortable and have her freedom. What if the husband is away, and only the brother in law is home.
From a shar'i perspective, it could be haram for the wife and brother in law to be alone, especially for excessive times, or over nights.
So, the ideal situation is for the brother-in-law to hopefully get married, or live with other single men in shared accommodation, and this does not mean anyone is being disrespectful or accusing or immoral conduct, etc.
The wife is entitled to ask for the brother not to live with them, and she has that right.
And Allah knows best.
If you know that your brother would be ok with you using his amanah in a wise and responsible way, and that you would return it back to your brother once he asks for it, then you are allowed to lend that money to your father.
And Allah knows best.
Allah, The Most Merciful, The Most Compassionate never created a human being forced to do something which is clearly forbidden by Him. He mentioned in Quran and previous holy texts the sever punishment of people of Sodom when they insisted on their evil practice despite the teaching of their Prophet Lut (AS).
It is false and wrong to claim that this act is not a choice. It is in fact a desire like the desire of fornication or adultery or any sinful sexual desire. There are people who have sexual desires towards married women or to their own real sisters or even towards animals. It is simply an evil desire which can never be justified.
If your brother believes in Allah, then how can he understand the sever punishment mentioned in Quran ( Sura Hood, verse 82) and ( Sura al-Hijr, verse 74) on those who used to do similar acts.
You need to talk to your brother and remind him about the facts mentioned in Quran and by the Prophet (SAWA) and Ahlul Bayt (AS). You may take him to trusted scholars who can explain to him that desire is not a destiny especially when it goes against the clear and essential facts of Islam and morals.
If he applies his intellect and think properly, he should then realise the truth, but if he refuses the truth and insists on evil desires, then you can not help him as he is not willing to help himself. Nevertheless, you should not lose hope any way. Keep on trying to explain to him, as well as praying to Allah (SWT) to guide him.
Well, people dream all sorts of things, some of them have meaning and some of them don't. If she is praying for this and you know she is praying for this, it makes sense that you might dream about it. Possibly your subconscious is thinking about it even if your conscious mind isn't.
If her brother has expressed an interest in marrying you, and it is a reasonable possibility for you to marry him, you could consider it. It is a blessing to have an opportunity to marry someone compatible whom you might have some trust in. It could be nice to marry a friend's brother (although keep in mind it can also change the nature of your friendship, especially if there are marriage problems). Of course there is no guarantee that the marriage would be happy but it is worth considering if you think he might be a compatible spouse. However you should make your decision based on the real life circumstances around you, not just the dreams.
If he hasn't expressed an interest in getting married then there is no reason to give it thought - he may or may not be ready to get married right now.
Anyway, you are lucky to have a friend who likes you so much that she wants you to be family. :)
She can seek guidance from any trusted person like her mother, sister, aunt, cousin sisters. If she has no trusted female to guide her, she can ask her father or brother to guide her.
Knowledge should be taken from any trusted source.
Yes, it is very good to perform the missed prayer of your deceased prayers. It will help him and you will also get great reward iA.
As she is not a Mahram for him, marriage with her is permissible if all other conditions are fulfilled.
