Is a mother entitled to take her divorced daughter's pension and alimony? And is a mother's prayer against her daughter answered? And is what the daughter is going through, in terms of bad circumstances, a punishment or a trial?

Your sister must be dutiful to your mother and treat her kindly, and not raise her voice at her, as that constitutes disobedience. She should also be patient and gently manage her mother to earn her pleasure. It is not permissible for the mother to take anything from her daughter's money except with her consent, unless she is in need, in which case she may take what suffices her need without harming her daughter. The sister is not obligated to spend on her mother as long as she has what she spends on herself. Divorce may be a trial or a punishment for a sin. One must be wary of children causing their parents to supplicate against them, for a parent's supplication against their child may be answered. Your sister's service to her mother in cleaning the house is due and she may not take payment for it.
