“It was said: ‘O
Messenger
of Allah, when should we stop enjoining what is good and
forbidding
what is evil?’ He said: ‘When there appears among you
that which
appeared among those who came before you.’ We said: ‘O
Messenger of
Allah, what appeared among those that came before us?’
He said:
‘Kingship given to your youth, immorality even among the
old, and
knowledge among the base and vile.’”
Sunan Ibn Majah Book 36, Hadith 90
