Condoning a haraam

Q: A Muslim family adopted a female child after birth. Her mother was a Christian. They brought her up as Muslim. Now she is 30 years old and wants to marry a Sikh boy. Adopted parents are in a dilemma trying to persuade her but she is adamant to Mary Sikh boy. They told her they have nothing to do with her. Adopted parents want to know can they go with her to the Registrar's Office and stand as witness and later bring her home with the Sikh boy and members of her immediate family and offer them food then she goes away not to return in future. Is this acceptable or is it haram? Please advise. 

Husband being over friendly with na mahram women

Q: Am I wrong to feel hurt and upset when my husband who claims to be innocent at home is over friendly when meeting female family members or
friends of mine outside. He also likes to play around and touch, poke, prod my mother, sister in law, cousins and thinks he's just playful and innocent and thinks nothing of it. I see more to his behaviour and feel disgusted. He even accidently bumps into females but I know its on purpose. What is wrong with him? Or am I wrong for being so angry and hurt?

Slavery

Q: I want to know the concept of kaneez/loundi in Islam. Is this rule still applicable like the previous age? Or that was for the present time? If this practice has been stopped then how? What does the Qur'an say about it?

Wudhu breaking with a drop of urine

Q:

  1. Someone told me that if only a drop of urine comes out you still have your wudu because a drop is less than a penny (coin), is this true?
  2. All impurity which is less than 3 to 5 centimetres in diameter is excused. I am sure two drops of urine on your clothes will not make a circle which is more than 3 centimetres, is that true?
