What is the ruling of the Sharia regarding my situation, given that I am unable to marry due to my financial circumstances, and I fear falling into zina due to the abundance of temptations, and thinking about this matter has begun to greatly affect my life?

This worldly life is a realm of trial and tribulation. The greatest jihad is the struggle against one's own self, and the greatest patience is patience in abstaining from desires. Therefore, it is advisable to be patient and to rely on Allah by marrying a religious woman, with certainty that Allah will enrich the married person from His bounty, as He promised in the verse: "And marry the unmarried among you and the righteous among your male slaves and female slaves. If they should be poor, Allah will enrich them from His bounty. And Allah is all-Encompassing and Knowing." If one is unable to marry, then one should fast, for it is a protection, a lowering of the gaze, and a safeguard for one's chastity, as the Messenger of Allah, peace and blessings be upon him, said: "O young men, whoever among you can afford to marry, let him do so, for it is more lowering to the gaze and more protective of the private parts. And whoever cannot afford to do so, let him fast, for it will be a shield for him." One should also avoid places of temptation, occupy oneself with beneficial work, and frequently supplicate and humble oneself before Allah, and fear Allah, for He makes a way out for whoever fears Him.
