How can a university student marry someone well-off to avoid widespread temptations?

If "facilitated marriage" means a legitimate contract that fulfills all conditions and pillars, with the woman waiving her right to housing, then there is no harm in it. If you are unable to marry, then you must fast, as the Prophet (peace be upon him) said: "O young people, whoever among you can afford to marry, let him do so, for it helps him lower his gaze and guard his chastity. And whoever is not able to do so, let him fast, for it will be a shield for him." We advise you to fear Allah, and there is no harm in resorting to serious marriage websites that adhere to Islamic guidelines.
