Abu Huraira reported God's Messenger as saying, "On the night when I was taken up to heaven I came upon people whose bellies were like houses and contained snakes which could be seen from outside their bellies. I asked Gabriel who they were and he told me that they were people who had practised usury.”
‘Ali said he heard God’s Messenger curse those who took usury, those who paid it, those who recorded it, and those who refused to give sadaqa; and he used to prohibit wailing.
