Q: I am writing this email because someone known to me is facing a strange situation and have insisted me to ask you this question. He is already married but have contracted nikah with someone else as well. However, when he committed the second lady about nikah, there wasn't any witness to that. Soon after that promise (or whatever you call it) the lady called her father and told about it. Father called the person and showed his agreement to her daughter's decision. Then they publicized this agreement to their family members. The first wife of the person called the lady and discussed various matters about her husband's marriage with the lady. Subsequently, the first wife announced that in their family. everyone accepted this decision. However, till date no formal document has been signed.

Now a million dollar question is about validity of this nikah. Please comment in the light of Quran and Sunnah.

Q: My father in law asked his daughter in front of myself and my two uncles whether she agreed to marry my brother. She allegedly replied 'yes.' My wife seen her sister nod her approval. My two uncles both heard the reply but I neither heard the question nor the reply because it was done in such a soft tone. Subsequently, in my presence and my brother in laws presence she was asked again to clarify. This time I heard the reply. My question is that tomorrow at the Musjid my uncle and I are witnesses to this marriage on the documentation that the girl signed. My uncle and I will also have to sign the same or another document.

1. Will the marriage be valid based on the fact that, when asked by the Imam, both witnesses on the documentation, my uncle and I did not both hear the girl say yes at the same time, i.e. I heard her say yes about half hour later, when the girl was asked again.
2. Is it permissible for me to sign the document saying I was a witness and say so when asked by the imam.

Q: Our Nikah was conducted by a Barelwi Imam as my wife's family follow them. Is there anything to worry about, such as the validity of the nikkah due to it been conducted by a barelvi imam? I don't think I have to investigate what exactly people's beliefs or statuses are. Can I just assume the best and leave the matter?
