Copulating in the streets is among the signs of the Hour

It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that he said: The Hour will not be established until Allah Almighty sends a wind which will not leave anyone in whose heart there is even an atom's weight of piety or understanding except that it will take his soul. Then every people will join what their forefathers used to worship in the Jahiliyyah, and only the rabble and base among people will remain, who will neither enjoin good nor forbid evil. They will copulate in the streets as animals do. When that happens, the wrath of Allah upon the people of the earth will become severe, and He will establish the Hour.

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that one night the Prophet (peace and blessings be upon him) was praying when suddenly he stretched his hand forward and then drew it back. We said: O Messenger of Allah! We saw you do something in this prayer that you did not use to do before. He (peace and blessings be upon him) said: "Yes. Paradise was presented to me, and I saw in it a grapevine whose clusters were hanging low. I wanted to pluck some of them, but it was revealed to me: 'Step back', so I stepped back. Then the Fire (Hell) was presented to me between me and you, until I saw my shadow and your shadows in it. So I gestured to you to step back. Then it was revealed to me: 'Leave them as they are, for you accepted Islam and so did they, you emigrated and so did they, and you strove in jihad and so did they, and I did not see any superiority of yours over them except through prophethood.' So I took this incident to mean the tribulations that will befall my Ummah after me."
This hadith has a sahih (authentic) chain, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) that he was with Maslamah bin Mukhallad when he said: "The Hour will be established only upon the worst of creation; they will be worse than the people of Jahiliyyah (pre-Islamic ignorance). They will not call upon Allah for anything except that it will be turned back upon them." While they were engaged in this conversation, Sayyiduna Uqbah bin Amir (may Allah be pleased with him) arrived, and Maslamah said: "O Uqbah! Listen to what Abdullah is saying." Uqbah said: "He knows best. As for me, I heard the Messenger of Allah (peace and blessings be upon him) say: 'A group of my Ummah will continue to fight upon the command of Allah, prevailing over their enemies; those who oppose them will not be able to harm them, until the Hour comes upon them while they are in that state.'" Then Abdullah said: "Yes (it is so). Then Allah Almighty will send a wind whose scent is like musk and whose touch is like silk. It will not leave any soul in whose heart there is even the weight of a mustard seed of faith except that it will take it. Then only the worst of people will remain, and upon them the Hour will be established.
This hadith has an authentic (sahih) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that he said: "Among the last events concerning the Ka'bah is that the Abyssinians will attack the House (of Allah), and the Muslims will set out towards them. Then Allah Almighty will send upon them a wind from the east, and Allah Almighty will not leave any servant in whose heart there is even the weight of a speck of piety except that He will take his soul, until, when they have been emptied of their good people, only the rabble will remain, who will neither enjoin good nor forbid evil. Every tribe will return to the idols that their forefathers used to worship and will begin worshipping them, until they will copulate in the streets just as animals do. Then the Hour will be established upon them. So whoever informs you of anything after this has no knowledge of it."
This hadith has an authentic (sahih) chain of narration on the condition of the two Shaykhs (Bukhari and Muslim), but it is mawquf (a Companion's own statement).

Sayyiduna Abdullah bin Buraydah narrates from his father that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, Allah Almighty has a wind which He will send at the end of every hundred years, and it will take the soul of every believer."

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "A time will come upon my Ummah in which the reciters (of the Qur'an) will be many while the jurists (those with deep understanding of the religion) will be few; knowledge will be taken away and harj will become widespread." The Companions asked: "O Messenger of Allah! What is harj?" He (peace and blessings be upon him) said: "Killing among yourselves. Then after that a time will come in which people will recite the Qur'an but it will not go beyond their throats. Then after that an era will come in which the hypocrite, the disbeliever and the one who associates partners with Allah will dispute with the believer using the very same kind of words that the believer (apparently) says."
