It was narrated that Anas bin Malik said:
"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.'"
