Why are my prayers not answered, and in fact the opposite of what I prayed for occurs, even though I have taken the means to ensure their answer? Am I "unlucky"? Is my selling of gold and spending my personal money on my treatment considered extravagance, for which I will be punished, and is expiation required? Is taking from my father's money without his knowledge forbidden or disliked?

A Muslim's supplication, as long as it does not involve sin or severance of kinship ties, will not be lost. It will either be answered swiftly, or stored for the Hereafter, or avert some evil. A believer, upon facing a calamity, says: "Qaddara Allahu wa ma sha'a fa'al" (Allah has decreed, and whatever He wills, He does). The acceptance of a supplication requires observing its conditions, taking the necessary means, and avoiding impediments. Pessimism and omens are forbidden in Islamic law.

Children must honor and obey their parents in what is good, and not fall short in their rights, even if the parents fall short in their children's rights. It is not permissible for parents to supplicate against their children unjustly, especially to curse them.

Good deeds must be done sincerely for the sake of Allah alone. Abandoning good deeds for the sake of people is showing off (riya'), and performing them for the sake of people is polytheism (shirk).

A father's failure to provide obligatory maintenance when he is able is not permissible. It is permissible for a person who is entitled to maintenance to take from his wealth, in a reasonable manner, what suffices him and his children. If the children have sufficient wealth, their maintenance is not obligatory upon the father.

If you have wealth, then you must spend on yourself from it. Your father is not obligated to provide for your maintenance or medical expenses. It is not permissible for you or your mother to take from your father's wealth without his permission and consent if your mother is divorced and her waiting period (iddah) has ended.
