I will narrate to you a Hadith and none other than I will tell you about after it. I heard Allah's Messenger (ﷺ)saying: From among the portents of the Hour are (the following):-1. Religious knowledge will decrease (by the death of religious learned men).-2. Religious ignorance will prevail.-3. There will be prevalence of open illegal sexual intercourse.-4. Women will increase in number and men will decrease in number so much so that fifty womenwill be looked after by one man.
