Custody of children after divorce

Q: I am a divorced woman with two minor children. I had been through a difficult marriage wherein I was physically, verbally and mentally abused. Presently my children are with me. My ex-husband and his parents are demanding that I send my children to spend the day with them or allow them to take them for a drive or shopping etc. Due to my history I`m not happy with this. They claim that I am depriving them of their Islamic rights. Can Mufti saheb please advise us with the shar`i ruling in this matter?

Husband becoming a Sikh

Q: I am thinking about marrying a woman who has a son already from a different person who is a sikh. I know its not allowed to marry someone out of religion. But the person who was married to her converted to Islam and did nikah but after couple of years he turned back to sikhism. Now the problem is where she stands at the moment. And she is also not divorced by him too. So can I still do nikah with her because its also not allowed to do nikah on top of the nikah as I know according to Islamic point of view. Moreover she is older than me almost 17 years but my intention is only to ease her problems and give her a happy life. Your advise will also help me a lot in this matter.
