Why is the husband not obligated to pay for the medicine, even though these are necessary items?

The questioner:
He says: Honorable Shaykh, may Allah grant you success, why is the husband not obligated to pay for the medicine and the doctor's fee for his wife, even though this is among the necessary things?

The Shaykh:
It is not part of the financial maintenance. This is not part of the financial maintenance, and this is not a permanent thing. This is something sudden. This is sudden, and it is not a permanent thing.

The questioner:
He is obligated to do so. As for his doing this, it is a matter of chivalry and good marital conduct.

The Shaykh:
Do you understand that it is forbidden for him to treat his wife and buy her medicine? No, this is part of good marital conduct, and he should treat his wife and buy her medicine. It does not reach the point where it becomes obligatory, but if he refuses, he is not obligated. If he refuses, he is not obligated, because this is something sudden. Yes.
