Q:
1. If a proposal and acceptance take place between a man or woman so are they married. Is this valid or legal in shariah.
Once in a TV program I heard that if a Muslim man and woman accept their proposal and accept each other then they are married and nikah takes place even if no one is present in between them. He said that this is called Nikah Ijaab and Qabool. Ss this true?
2. I also heard that for nikah Ijaab and Qabool permission, wish or willing of a woman's father is necessary.
3. If a man and woman accept each other in the presence of her mother and her 14 years old brother, so in this case nikah takes place or not?
4. If a father of a woman wishes to marry her daughter with his sister son (Nephew) and both the girl and boy are fiancee and fiance and both the parents wish to marry them but both girl and boy accept each other saying nikah words in the absence of any witness and both parents are also not present at that time so in this case nikaah takes place or not?
