Is a person punished for not communicating with or visiting their mother if the mother prefers other children, does not ask about her sick daughter, and does not stand by her in her ordeal?

It is recommended to be patient, supplicate frequently, and ask Allah for relief. Parents hold a great status, especially the mother, due to the immense nature of her rights and the hardship she endured during pregnancy, childbirth, and breastfeeding. Therefore, it is impermissible to disobey or abandon them, even if they commit injustice; rather, one must treat them with kindness. The harm inflicted by the mother upon her children and grandchildren is an unusual matter whose cause should be identified. If there is a reason, it should be addressed. If there is no reason, she should be dealt with gently and advised kindly, and the help of some close relatives should be sought. As for the siblings, you should advise them and remind them of kinship ties. If they respond, then that is well and good. Otherwise, it is permissible to abandon them, while considering the benefit. As for the maintenance of a divorced woman who has no wealth, you can refer to Fatwa (definition) No. 92610.
