Coming back to fatwas and fantasies and the reality of Halala; the fact is that the prevalent practice is nothing but a heresy in itself. According to the correct opinion (and what exists in the whole of the Muslim world sans the subcontinent) the real case is that:
'If a man divorces his wife and the wife (who is now a stranger to him in relationship) leaves him and goes back to stay with her parents; this man cannot marry her again. Later if that woman herself wishes to marry someone else of her choice, she can marry (with a intention like the intention of any other normal Islamic marriage that this marriage is forever) and both these wife/ husband should never intend to do this as a temporary marriage (because in Islam there is no temporary marriage). After this second marriage of the woman if (by rare chance), this second marriage of this woman (naturally) breaks or doesn’t work either or she takes Khula (separation) - then in that case, she is free to return to her first husband and remarry him, if she likes. In this entire chanced reunion, the first husband must not have any role to play even remotely. If any of these actions was pre-mediated then it will make the whole exercise a farce and none of these latter two marriages will count as valid'. This is the correct process.
