Is it permissible to issue a pronouncement of divorce on a woman during her menses? Is such a divorce valid?

Dear scholars, my question relates to changing name, I mean, is it necessary for newly converts to Islam to change their names or they can keep their Christian or any previous names?

I think my brother is gay, and I say this because of the way he talks, the way he does his hair, the kind of clothes that he wears and the things that he is interested in. One time I used his USB and saw some pornography on it, including anal intercourse, and I do not know whether it was between two men, because I closed it quickly and erased the file. I asked him about it and he said he did not know where it came from, but in the end I found more in his room. I also checked his personal computer and I found out that he visits gay websites in the country where he is studying. My question is: do I have to advise him and warn him about the bad consequences of this sin?

I want to join an islamic society in europe. This society includes a mosque and dars.
The shura demands a membership fee. Is this halal?

Sometimes a person suffers from thinking of some sin, and other thoughts that come from the whispers of the Shaytaan and the nafs. Will he be requited for whatever crosses his mind, and will it be written in his record, whether it is good or bad?

My question is regarding distributing leaflets/pamphlets for dawah purposes that contain Quranic verses. It is likely that many of them will end up on the streets or bins after being distributed. Isnt this wrong and should this discourage us giving out such material? Also, is this ok, considering that the targeted recipients are non-muslims who are impure?

I read your answer about prayer whilst doing surgery or afterwards. I work as a doctor and the day is very short in Canada during the winter; Maghrib comes at 5 p.m. Hence the time between the prayers is very short and I do not know how the surgeon can do his work when this time is very short. Hence I think it is better to make the prayers up afterwards. What is your opinion on that?

My husband and my family do not get along, they are not muslim, although I have invited them many times, nor do they understand Islam.  My husband wants to prevent my parents from seeing my children because he feels they have cursed Allah, although they have not done so.  Is this allowed?

How can we help a child to know his Lord?

I want to make my children keen to pray, because they will pray once then forget about prayer many times. I always advise them and pray to Allah to guide them. How can I encourage them and make them love prayer?.
