Does the husband’s share of the profits from a store, which the wife had worked for three years to develop without financial compensation, enter into the heirs’ estate, given that she had collected a sum for her husband in exchange for his waiver of his share of the profits before his death?

1. The merchandise in the store is divided equally between the wife and the husband, and the heirs have their share from the husband's portion.

2. The fifty thousand that the wife collected does not waive the heirs' right to their share of it from the husband, because his promise to relinquish it was not fulfilled due to his death.

3. If the original agreement was only a partnership in capital, then the wife is entitled to only half, and her feeling of being wronged now does not affect this. If the the agreement also included work, and the husband was negligent, then the wife has the right to demand a fair wage (ujrat al-mithl) or a reduction of the husband's share of the profit in exchange for her work.
