Some people don't know that they are despising the religion & not the person or tradition. It is not necessarily that 2 wives to be in 1-roof. What you should ask yourself is that why other people have a woman which is illegal & their religion have no solution for this problem whereas Islam has only the solution. Come to think of it and have a study of other religion for comparative religion rather than sticking to the religion of your forefathers or country which may b u r n the wrong direction?
The labor head has the prerogative in approving 2 wives to stay and both to have iqama or family visa depending on the status or capability of the person. Thanks.
