What are the consequences for a wife's division and maintenance rights when she travels with the husband's permission?

Primary text

If a wife travels with her husband's permission for her own needs, such as trade, visiting, voluntary Hajj, or Umrah, her rights to maintenance (nafaqah) and division cease. This is because the division is for companionship, and maintenance is for granting enjoyment, both of which are rendered impossible by her travel initiated by her, analogous to impossibility arising before consummation. If the husband summons her or orders her relocation for his need, her rights to maintenance and division do not cease because she did not cause the prevention of enjoyment; rather, it occurred due to his action, similar to a buyer not forfeiting the right to payment if he destroys the item before receiving it. In this case, she is compensated according to the time he spends with her co-wife. If she travels with him, she retains her rights concerning both wives.
