Is a young man considered sinful if he refuses to marry due to his desire to complete his higher education or to work to cover his expenses, despite his father's insistence, his father being able to cover the expenses, and his father threatening him with anger and cutting ties with him?

Islam encourages marriage due to its benefits in protecting one's chastity, safeguarding one's private parts, lowering one's gaze, and increasing progeny. Your father has commanded you to marry, and obeying him in this regard is obligatory. We advise you to hasten in fulfilling your father's request, for perhaps Allah will grant you success in your studies through this obedience, and marriage will help you complete your education in the best way, due to the stability it brings to the soul and its ability to curb youthful recklessness. Furthermore, you do not know when you will die, so hasten and seize the opportunity, for in it lies the pleasure of Allah and the pleasure of your father.
