A hadith regarding the issue is as follows:
أَتَيْتُ لَيْلَةَ أُسْرِيَ بِي عَلَى قَوْمٍ بُطُونُهُمْ كَالْبُيُوتِ، فِيهَا الْحَيَّاتُ تُرَى مِنْ خَارِجِ بُطُونِهِمْ، فَقُلْتُ: مَنْ هَؤُلَاءِ يَا جِبْرِيلُ؟ قَالَ: هَؤُلَاءِ أَكَلَةُ الرِّبَا
On the night in which I was taken on the Night Journey (al-Isra), I came to people whose stomachs were like houses, in which there were snakes that could be seen from outside their stomachs. I said: 'Who are these, O Jibril?’ He said: 'They are the ones who consumed usury (interest). (Ibn Majah, Tijarat 58; Musnad, 2/353, 363)
This hadith is an exemplary lesson for those who consume riba (usury/interest).
Hereby, we will address the believing brothers who continue consuming interest without repenting by advising them to call themselves to account:
O brother who consumes interest! Is it worth?
Is it reasonable to show consent to such a big penalty in the hereafter for a small and ephemeral interest in the world?
If you do not give up consuming interest, you will be resurrected like that on the Day of Judgment. You will have a stomach as big as a house. Snakes will move in it. Will you be able to put up with it? Definitely not.
Then, come and repent of this sin since there is still time for it.
