' "'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 Jibra’il?’ He said: 'They are the ones who consumed usury."'
Sunan Ibn Majah Book 12, Hadith 137
