Background : Muslim couple with 2 yr old son. Married 3 years then he walks out then comes back to throw them out. This came totally out of the blue, suddenly he says this isn't what he thought marriage was all about and she is a lousy, ungrateful, wife/mother, only after his money.
She goes home to her Mum with her son and he comes and takes him out a couple of times a week.
In a usual UK divorce, the court decides on custody but in the Islamic system there doesn't seem to be rules?
