قَالَ ٱلْمَلَأُ ٱلَّذِينَ ٱسْتَكْبَرُوا۟ مِن قَوْمِهِۦ لِلَّذِينَ ٱسْتُضْعِفُوا۟ لِمَنْ ءَامَنَ مِنْهُمْ أَتَعْلَمُونَ أَنَّ صَٰلِحًۭا مُّرْسَلٌۭ مِّن رَّبِّهِۦ ۚ قَالُوٓا۟ إِنَّا بِمَآ أُرْسِلَ بِهِۦ مُؤْمِنُونَ
The chieftains of his people, who were scornful, said unto those whom they despised, unto such of them as believed: Know ye that Salih is one sent from his Lord? They said: Lo! In that wherewith he hath been sent we are believers.

Knowledge
Chapter: (What is said regarding) the disappearance of the (religious) knowledge and the appearance of (religious) ignorance
Narrated Anas:
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 women will be looked after by one man.
