(110) باب يَقِلُّ الرِّجَالُ وَيَكْثُرُ النِّسَاءُ
Narrated Anas:
I will narrate to you a Habith I heard from Allah's Messenger (ﷺ) and none other than I will tell you of it. I heard Allah's Messenger (ﷺ) saying, "From among the portents of the Hour are the following: Religious knowledge will be taken away; General ignorance (in religious matters) will increase; illegal Sexual intercourse will prevail: Drinking of alcoholic drinks will prevail. Men will decrease in number, and women will increase in number, so much so that fifty women will be looked after by one man."
