Will my acts of worship be accepted and my supplications answered despite my mother's displeasure with me, as she invokes evil upon me?

Strive in obeying your mother and earning her pleasure. If her situation does not change, then there is no sin upon you. Her unjust curses against you do not prevent your acts of worship and supplications from being accepted, for Allah the Almighty wrongs no one, and she is sinful for cursing you without cause. The Prophet, peace and blessings be upon him, said: "The servant will continue to be answered as long as he does not pray for a sin or cutting off ties of kinship." This ruling applies equally to anyone who curses unjustly. However, if the curse is just, then it is permissible, but refraining from it is better. Continue to obey her righteously and treat her kindly.
