Will a mother's supplication against her daughter to be deprived of children be answered, even if the mother is far from religion and does not observe its obligations?

The supplication of a father or mother against their child is answered, unless the child is dutiful and the supplication is unjust and aggressive. In such a case, it is not answered, due to the saying of the Prophet, peace be upon him: "A servant will continue to be answered as long as he does not pray for a sin or for the severance of kinship ties." It appears that this applies to a disobedient child who is excessive in their disobedience. The mother erred by supplicating, and it cannot be definitively asserted that the deprivation of a child is due to the mother's supplication, especially since she regretted it. The questioner should focus on guiding her mother to the path of Allah, being dutiful to her, and increasing in repentance and seeking forgiveness, as these are among the reasons for being blessed with a child.
