Nikaah & Marriage Issues

Q: I have a "Memon" friend who wants to marry a "Surti" girl. His parents do not wish this to happen. I obviously know that the parents are in the wrong to draw a divide in this manner as they are both Muslim. However, I am also aware that the blessings of the parents are important to a marriage, and going against them will most probably result in a severing of family ties. Firstly, should I try to speak to the parents and/or mediate between the parties. And secondly if this fails do I still encourage the marriage or do I encourage him to respect his parents' wishes. Please advise

Q: We were gifted with a baby girl 6 months ago and now yesterday we came to know that my wife is again pregnant. She is suffering from Bipolar Disorder, after the birth of 1st child, and is taking medicine for cure. If the medicine is stopped, it might harm her according to doctors. She is under deep mental stress and if the medicine is stopped it will be further problem. So I request your good self that can we abort the foetus to avoid bigger problems in my family life. We should have taken care before but I was not knowing that she is under this kind of mental depression as I was away for 5 months. I am under deep tension since yesterday and hope you will guide me to the right path, Insha Allah.

Q: What is the correct dress code for a bridegroom at his nikah? Is it mandotary for him to be dressed formally? ie. with a waist coat, formal
shoes, collared kurta. etc. Or is it preffered that he dresses neatly in Islamic attire, for example with just a kurta, turban, and normal non-formal shoes?
