Salaam Alaykum.. Whenever there is someone's nikkah they mention the (father's name) of the bride or the groom.. So if I adopt a child and raise him well,And kept it as a secret.. In his/her nikkah do we have to mention the actual father's name or my name(the father who raised the child)??
The important thing is that it is clear who the groom is, i.e. he is known to be the actual person being married.
He can use the name and surname that he is normally known by and that is fine
