3. If the answer to question 2 is 'yes' and if the parents of both the girl and the boy agree for their marriage in future without being aware that the girl and boy have already entered into nikah, (and the girl and boy do not want to reveal this fact to their parents), can they enter into nikah again when the marriage takes place for the purposes of registration in union council?

Q: I was divorced 20 years back and I have 2 daughters from my first marriage. My parents brought them up without any help from my ex husband.

After divorce, he got married and I also got married. Now my first daughter is getting married. For some time my ex husband is contact with my daughters so she asked her father to be her wali in her marriage but he refused all of sudden.

My father, their maternal grandfather (nana) became her wali from the age of 2 since he only taking care of her.

My question is whether my daughter's marriage is valid or not?

Q: A relative was investigating a girl for my marriage. He learnt from a very reliable source that the girl was sexually molested when she was a child. When my parents learnt that the girl was molested as a child, they said that we should not investigate her anymore for my marriage.

Is this correct behavior? Is this a valid reason for not considering someone for marriage? In my opinion, it appears unfair to her as she was a na-baligh at the time. I do understand well that child sexual abuse victims often carry traumatic memories and emotional symptoms well into adulthood. But will this mean that one should not consider such a person for marriage entirely before looking at anything else, like character, morality, hayaa, etc.?

Q: I would like to know if a hanafi girl has found a suitable partner, such a partner that is a Muslim, one who performs his salaah, he is capable of financially providing for her and fulfills all the requirements of nikaah, however her mother refuses for her to make nikaah to such a boy without any solid and valid excuse, will it be allowed for her to make nikaah to him without the happiness of her mother as the mother is not being reasonable?
