When is it Waajib for the Wife to Do the Cooking?

1. In the case of the wife being ill and she cannot do the household work, the husband will have to arrange for food to be cooked and given to her.
2. Similarly, if the wife is from a very affluent family in which the females do not do the cooking themselves, it is below their standard for the females to do the cooking, in this case too, the husband will have to arrange for food to be cooked.
3. If she is neither ill nor is she from such a wealthy family who do not the cooking themselves, then it is waajib (obligatory) upon her to do the household work herself.
4. The responsibility of the husband in this case (3) is merely to provide the stove, oven, pots, etc. and the groceries for her to do the cooking.
