Sahih al-Bukhari Book 74, Hadith 3
I heard from Allah's Messenger (ﷺ) a narration which none other than I will narrate to you. The Prophet, said,

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

On the night Allah's Messenger (ﷺ) was taken on a night journey (Miraj) two cups, one containing wine and the other milk, were presented to him at Jerusalem. He looked at it and took the cup of milk. Gabriel said, "Praise be to Allah Who guided you to Al-Fitra (the right path); if you had taken (the cup of) wine, your nation would have gone astray."
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).
