Is the marriage of a young man studying abroad, without his parents' consent, considered an act of disobedience, given his desire to marry to avoid the temptations prevalent in the country of study?

We advise you to strive in convincing your parents of the necessity of marriage for the sake of chastity and preserving oneself. You can also mediate through some relatives or people of religion and good character who have influence with them to discuss this matter with them. If that does not work, then there is no blame upon you for marrying without their consent; because you would be harmed by not getting married, and obedience to parents is not obligatory in matters that harm the child.
