Islamic countries

Q: I just need to ask you about something and that is I have found out that most of the Muslim countries are secular muslim countries and its government are secular government. I just want to ask can we call those countries and its people muslim countries and are we as muslims allowed to make the countries into muslim countries and muslim state or khalifa and make the law into sharia law and are we allowed to over throw the government and make it into muslim government and make the law into Sharia law? I have found out that the people in those muslim secular countries and its secular government that they are muslim but do we call them muslim people and muslim countries or what do we do and what do we call them?

Does a Musjid have more virtue than a jamaat khaana?

Q: If a jamaat khana is on its own property, with the property being on a 'educational trust' etc with trustees etc, like how a normal masjid would be, all salaah etc But due to the zoning not yet being passed through the municipality as a religious site, it has not yet been declared a masjid. If the permission is granted, immediately it would be a masjid. My question is, is salaah in this jamaat khana inferior to that performed in a masjid 5 minutes away?

Nikaah breaking through one of the spouse becoming a murtad

Q: I am currently going through a very bad period and I needed your advice. I am originally from Pakistan and I came to UK 10 years ago. I married my wife just over four and a half years ago and she reverted to Islam. During our first year of marriage I did something bad which goes against the teachings of Islam (abortion) and since then my wife has not forgiven me. Since then she has also stopped practising Islam. Till date she does not respect me and always sheds mental abuse calling me names and always reminding me of what i did. Currently we have got 2 kids (2 1/2 year old and 1 1/2 year old). I have tried my best to make her happy but she argues with me multiple times during the day and shows a lot of anger towards our kids as well. Today as an example she has been arguing with me all day calling me all sorts of names and bringing up things from the past. I have apologized to her multiple amount of times but there are no signs of her stopping and all this is having an adverse effect on our lives. I am writing to you with the hope of getting some advice of what would be the best course of action islamically. I greatly love my 2 girls (kids) and as a result I have not divorced her as she will not let me see them and if i remarry she has said she will ensure that she breaks all ties with me and she will not let me see the kids. I am deeply concerned as she would bring the kids up catholic as her family is athiest. Is there any suggestions which you can provide which might help to ease my situation? Similarly is there any wazifahs I can read so that we can be a happily married couple once again.

Sale item not being specified

Q: I went to buy some jewellery. A salesman there told me that there is a scheme where I have to pay 11 instalments in advance and the 12th instalment will be paid by the jewellery company as a bonus or discount. I can then buy any gold jewellery of my choice after 11 months. Is this allowed in Islam?
