Sahih al-Bukhari Book 74, Hadith 4
The Prophet (ﷺ) said, "An adulterer, at the time he is committing illegal sexual intercourse is not a
believer; and a person, at the time of drinking an alcoholic drink is not a believer; and a thief, at the
time of stealing, is not a believer." Ibn Shihab said: `Abdul Malik bin Abi Bakr bin `Abdur-Rahman
bin Al- Harith bin Hisham told me that Abu Bakr used to narrate that narration to him on the authority
of Abu Huraira. He used to add that Abu Bakr used to mention, besides the above cases, "And he who
robs (takes illegally something by force) while the people are looking at him, is not a believer at the
time he is robbing (taking).
I heard from Allah's Messenger (ﷺ) a narration which none other than I will narrate to you. The Prophet, said, "From among the portents of the our are the following: General ignorance (in religious affairs) will prevail, (religious) knowledge will decrease, illegal sexual intercourse will prevail, alcoholic drinks will be drunk (in abundance), men will decrease and women will increase so much so that for every fifty women there will be one man to look after them."
"Alcoholic drinks were prohibited (by Allah) when there was nothing of it (special kind of wine) in Medina.
