Must I give my father from my money and monthly income, knowing that he is not religiously committed and does not help me with marriage expenses, and that what I earn is not enough to cover the needs of marriage and furnishing the new home, and I need this money to become independent in my life?

Reviling God or His religion is an act of disbelief (kufr). As for a father reviling the Divine Being and abandoning prayer, this is a great calamity that necessitates advising him and supplicating for his guidance. It is permissible for a father to take from his son's wealth if he is in need, provided it does not harm the son. One should be gentle with the father, assist him, and fulfill his requests whenever possible. If not possible, then one should deal with him tactfully. It is important to strive to marry into an understanding family that will facilitate the marriage process.
