Sahih al-Bukhari Book 34, Hadith 37
When the last Verses of Surat al- Baqara were revealed, the Prophet (ﷺ) recited them in the mosque and
proclaimed the trade of alcohol as illegal.
The Prophet (ﷺ) said "Certainly a time will come when people will not bother to know from where they earned the money, by lawful means or unlawful means." (See Hadith no. 2050)
The Prophet (ﷺ) said, "This night I dreamt that two men came and took me to a Holy land whence we proceeded on till we reached a river of blood, where a man was standing, and on its bank was standing another man with stones in his hands. The man in the middle of the river tried to come out, but the other threw a stone in his mouth and forced him to go back to his original place. So, whenever he tried to come out, the other man would throw a stone in his mouth and force him to go back to his former place. I asked, 'Who is this?' I was told, 'The person in the river was a Riba-eater."
