Is it permissible for the mother to prevent the child's grandmother from seeing her due to the grandmother's instigation of problems and her desire to monopolize the child? For how long is the mother entitled to prevent the grandmother from seeing her granddaughter? And what are the grandmothers' rights regarding their grandchildren?

It is necessary to prioritize kindness and good treatment towards the grandmother, and to endure her harm with patience, because reconciliation is better, and gentleness adorns things. The grandmother has the right to see her granddaughter, and depriving her of that without a strong justification is considered a transgression. Respecting the grandmother contributes to honoring the husband and gladdening his heart, and may restore harmony between the spouses. The grandmother can be managed by flattery, embracing her, and kissing her head to remove hatred. It is not permissible to prevent the grandmother from seeing her granddaughter unless harm to her is feared, and it is preferable for her visitation to be under supervision. The husband should be involved in solving problems with his mother because he is most capable of influencing her. The duration of the visit is determined by customs and the circumstances of each case. The rights of grandmothers over their grandchildren include respect, appreciation, kindness, maintaining ties, anticipating needs, and service. Seek reward from Allah for the grandmother's prayers against you, and do not treat her in kind; rather, supplicate for her guidance.
