Surah 60. Al-Mumtahinah, Ayah 11

Lit., "and you are thus taking your turn", i.e., like the unbelievers whose wives have gone over to the Muslims and renounced their erstwhile faith.

Since, as a rule, the unbelievers cannot really be expected to indemnify a husband thus deserted, the Muslim community as a whole is bound to undertake this obligation. As a matter of fact, there were only six such cases of apostasy in the lifetime of the Prophet (all of them before the conquest of Mecca in 8 H.); and in each case the Muslim husband was awarded by the communal treasury, on orders of the Prophet, the equivalent of the dower originally paid by him (Baghawi and Zamakhshari).

A very unlikely contingency, considering how much better position the women occupied in Islam than under Pagan custom. But all contingencies have to be provided for equitably in legislation. If a woman went over to the Pagans, her dower would be recoverable from the Pagans and payable to the deserted husband. If a woman came over from the Pagans, her dower would be payable to the Pagans. Assuming that the two dowers were equal, the one would be set off against the other as between the two communities; but within the communities the deserted individual would be compensated by the individual who gains a wife. If the dowers were unequal, the balance would be recoverable as between the communities, and the adjustment would then be made as between the individuals.
