Nikaah & Marriage Issues

Secret nikaah

Q: I would like to know my friend is sixteen and he is getting married to a girl who is sixteen. He is going to have his two friends as witnesses and he will give mahr and both the boy and girl will sign a contract. They both are Muslims. I wanted to know if the nikaah will be accepted as there is no guardian from the girls side because her parents says it's to early to get married.

Illicit behaviour

Q: If a man keeps bad faith for his sister in law although, he did not practically commit anything, but shows his interest in her verbally while communicating with her. Does this effect his nikaah in anyway?

Touching one's mother in-law with lust

Q: An accident occurred in bus journey some years ago, that is: my mother in law's seat was beside my seat. She was feeling ill because of some illness but I was feeling lust/desire but not highly exited. Then I probably touch her (not her private part). But I was mentally addicted by shaitan’s waswasa. She didn't know this was my situation. I had no idea before about marriage, mahrams and hurmat-e-mushara. After I came to know about hurtmat-e-musaahara, I repented and made Towba to Allah Ta'ala. Now I am very alert about shaitan’s waswasa. But mentally I am worried about that accident. Now my wife would be lawful? I have one daughter. Please clearly advise me.

Breastfeeding one's step son

Q: I have a question about my step son. What does Islam say about breastfeeding a step son (he is my husband's son, his mother has left this child in our custody). If I am not wrong, every child has a right to be breastfed according to Islam. So as a stepmother is it permissible for me to breastfeed him? Is it sawab or gunaah?
