If you have lost anything from your wives went to the Kuffar, then you give it to those who lost instead of giving to the husband of the believing women, you heed Allah with whom you are believing.
If the disbelieving women under the wedlock of believing men are going to the Kuffar, and are not giving back the dowry to their believing husband, then the believing women who are under the wedlock of disbelieving men came to the believers need not give back the dowry completely they had received from their disbelieving husband, instead they can give from it to the believing men what the disbelieving women didn’t give to the believing men, and the balance if there anything should only need to be given back to the disbelieving men. Today among the Fujjar who are reading these verses in Arabic Qur’an, marriage is conducted by giving dowry and ornaments from wife’s side without giving which is just opposite to the command of Lord’s Book. Among them are also divorce is happened without any reasoning just like changing the dresses. Thus the verses in Arabic Qur’an are going to argue and witness against them and will be pushing them to the Hell as explained in verse 9: 82. See explanation 39: 47-48; 42: 45; and 57: 22.
