Is it permissible for a mother to burden her son with expenses and demands, and to try to alienate him from securing the future of his children? And is the feeling of hatred towards her, along with the attempt to deal with her kindly, considered hypocrisy?

The husband is not obligated to give his parents or siblings anything that would deplete his wealth or exceed their basic needs, but he will be rewarded for doing so. Building a home for the children is a righteous act. Ibn Muflih said: "A dwelling is obligatory for a person and for those whose maintenance is incumbent upon him." The Prophet, peace and blessings be upon him, encouraged Sa'd to leave his heirs wealthy. The wife may advise her husband gently and wisely to balance spending on his family with saving money for his home and children. It is a sign of the wife's good character to be kind to her husband's family and to help him honor his parents and maintain kinship ties. Honoring the husband's mother is not hypocrisy but rather a sign of good character.
