Is the husband obligated to compensate one of his wives for the nights he spent with another, in the event that the first wife is ill and hospitalized, or the other wife goes to visit her family?

If the wife falls ill and remains in the hospital, she is not entitled to her share of the nights (qasm) for missing the marital right, nor does the husband have to make up those days for her. However, if she travels to visit her family or another place, then: if the travel was for her need, the husband does not have to make up what she missed. If the travel was for his need, then the husband does make up what she missed. If she travels with his permission for her need, then it is not made up for her. But if she travels with his permission for both their needs, her right is not forfeited.
