Q: Is it permissible to marry a guy who is a non Muslim and he wants to convert to Islam? Is a Muslim girl allowed marry him after he converts to Islam?

Q: I want to know if is a myth or real in Islam that a when a girl has her first period she should get married as soon as possible.

Q: People work hard to earn more money and make their duniya good, is the wife included in duniya or not? 

Q: If my mother forbids me but I almost convince my husband that I will do hijama, then is it permissible for me to do it? I don't live with my husband yet but soon we will be living together and I have an illness which can break our marriage and of course my mother doesn't know about this illness. And I have many other illnesses. So can I go without my mother's permission if my husband gives me permission?

If my husband again forbids me after getting convinced, can I go?

Q: If someones wife says that you don't have Imaan, does it have any effect on his nikaah?

Q: If a husband stops sleeping with his wife but the wife never wanted this, who will be questionable in the court of Allah?

Q: Can you help me on which date our marriage should be done in this month. I want to know the dates on which marriage can be done according to Islamic calender?

Q: Is it better to have more than one wife in islam? As in Quran the ayat starts with marrying two or three or four. If they cannot be just to more than one, only then they should marry one. And our Prophet and all the Sahabah (as far I know) had more than one wife. So is it more appreciated in Islam to have more than one wife?

Q: How should a wife's relationship be with her husband? To what extent should she love and respect her husband?

I have read somewhere that a man and womans relation should be limited because it harms one's iman the most. I don't remember exactly, but it was something like that.

In my life I feel like sometimes my thinking only rotates around him and his little ignorance or bad behaviour or telling me to improve myself (such as hair, weight, accent, etc.) these things make me so sad that I feel difficulty in breathing. I remain sad for a long time and I cannot concentrate in something. I constantly keep saying that he is bored with me or I am not pretty or he doesn't love me, etc. I know I shouldn't do that. But what should I do when I feel bad that my heart starts to ache?
