Cancelling a co-wife's share due to her illness

A: The basic principle states that justice among wives regarding housing, food, clothing, and spending the night is obligatory. You should fear Allah and be just to them according to your ability. If you want to favor any of them for the reasons you mentioned, you should kindly ask the other's permission. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
