"O believers! Do not consume interest, multiplying it many times over. And be mindful of Allah, so you may prosper."
-Qur'an 3:130
"and for their charging Ribā (usury or interest) while they were
forbidden from it, and for their devouring of the properties of the
people by false means. We have prepared, for the disbelievers among
them, a painful punishment."
-Qur'an 4:161
"Whatever you lend out in usury to gain value through other people’s
wealth will not increase in God’s eyes, but whatever you give in
charity, in your desire for God’s approval, will earn multiple
rewards."
Qur'an 30:39
"Those who consume interest cannot stand [on the Day of Resurrection]
except as one stands who is being beaten by Satan into insanity. That
is because they say, "Trade is [just] like interest." But Allah has
permitted trade and has forbidden interest. So whoever has received an
admonition from his Lord and desists may have what is past, and his
affair rests with Allah . But whoever returns to [dealing in interest
or usury] - those are the companions of the Fire; they will abide
eternally therein. Allah destroys interest and gives increase for
charities. And Allah does not like every sinning disbeliever. Indeed,
those who believe and do righteous deeds and establish prayer and give
zakah will have their reward with their Lord, and there will be no
fear concerning them, nor will they grieve. O you who have believed,
fear Allah and give up what remains [due to you] of interest, 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."
Qur'an 2:275-280
The Messenger of Allah (saws) cursed the one who consumed Riba, and
the oe who charged it, those who witnessed it, and the one who
recorded it.
-Jami At-Tirmidhi 1206
Riba is a major sin in Islam. No questions asked. You must do everything in your willpower to not enter interest. You must not engage in it, even if you're at the risk of homelessness. Insha'Allah, Allah will see how you're staying clear from such a major sin, He will aid you and grant you fortune. Keep making Dua.
