Entering Makkah without Ihraam

Q: I once performed umrah when I just became baaligh. My grandparents and I entered Makkah without being in Ihraam and also I did not wear proper shoes in Ihraam. However, all of this was done unknowingly, as I had not yet been taught that. Should I still pay a dam and what should one do if one cannot afford a dam?

How to dispose of interest

Q: I have an amount in a savings account and I am getting interest for it. Is it Haraam? I never used it but whenever I receive interest, I used to give
it to poor people what ever I received. Is it accepted in Islam? Will there be any benefit? Is it haraam for the poor people whoever receives interest amount from us?

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.
