‘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.
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.”
The last verse to be sent down was that on usury (Al-Qur’an 2:275) but God's Messenger was taken without having expounded it to us; so leave aside usury and whatever is doubtful.
