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.
‘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.
Anas reported God’s Messenger as saying, "When one of you makes a loan and the borrower sends him a present or provides an animal for him to ride, he must not ride the one or accept the other unless it is a practice they followed previously."
Ibn Majah and Baihaqi, in Shu'ab al-iman, transmitted it.
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.”
