Is it obligatory not to study at university due to the usurious borrowing involved, given that studying is the means to work and earn money with the aim of emigration and salvation of one's religion?

Migration from lands of disbelief is obligatory if a Muslim cannot openly practice the rituals of their religion; if they can, then it is not obligatory. Dealing with usury (riba) is one of the gravest sins, as Allah Almighty says: (O you who have believed, fear Allah and give up what remains [due to you] of usury, if you should be believers. And if you do not, then be informed of a war [against you] from Allah and His Messenger. But if you repent, you may have your principal – [thus] you do no wrong, nor are you wronged) [Al-Baqarah 2:278-279]. And the Prophet (peace be upon him) said: (The Messenger of Allah (peace be upon him) cursed the one who consumes usury, the one who gives it, its scribe, and its two witnesses, and he said: "They are all equal [in sin]"). Completing one's studies is not a necessity that permits dealing with usury; rather, one must seek a job to combine study and work. There is no obedience to parents in taking a usurious loan.
