Correct pronunciation

Q: When we say the Kalimah Laa Ilaha ILLAllah Muhammadur Rasulullah, then can we also say La Ilaha ILLAllah Muhammadun Rasulullah? With the nūn? Because in my local masjid there used to be a muezzin who used to say Ashadu Anna Muhammadun Rasulullah or Muhammadan Rasulullah, and the Imam said he was wrong and it should be said as Muhammadur Rasulullah.

Kissing one's daughter

Q: One day I was caressing my daughter (about 4 years old). Suddenly I felt little lust. Quickly I stopped caressing her and took her off. After this incident I repented and made tawbah to Allah Ta'ala. Does this incident affect my marriage?

Irregular bleeding

Q: If my wife is always having periods for 5 days. After 5 days can we can do 'intercourse'? Last week after 5 days, after confirming that there is no more bleeding and no signs of blood, we did. But after 2/3 hours suddenly bleeding starts, this was the first time it happened. What does Shari'ah says about it? I can't explain my question much but please give me a detailed answer as we are very concerned about this. We don't want to commit any sin.

Treating one's children equally

Q: My question is regarding maintenance. My husband and I have two daughters and a son that is four months old. My husband's ex wife has dragged him to court for maintenance numerous times and he has told the court he can not afford that which she is asking but can pay a lesser amount. The councillor in charge of his case has now told him to get a better job and that I should find a job to so that I can support our children and he must then support his previous child. I need to know what Shari'ah says regarding the fact that my husband must solely see to that child and not the children he has with me. His ex-wife has also on numerous occasions told him why did he have another baby when he can't support her daughter. And that her daughter was there first so she deserves everything. I'm quite shocked and hurt that she would be so towards my kids when we don't ask her for anything. She is married to a sheik and is in purdah but belittles my children when ever they appear in court.
