If he happens to divorce her and reclaim her twice and then divorces her again a third time, then he has no right to reclaim her in wedlock, that is if they both are so inclined, before joining another man in wedlock. If the second husband willingly divorces her, then and only then, are they absolved to reunite in wedlock if they both believe they are able to honour the limitations imposed by Allah. These are the limitations imposed by Allah; He clearly explicates them to those who reflect.
