It is narrated from Hazrat Anas (may Allah be pleased with him) that a person submitted in the court of the Prophet, "O Messenger of Allah (peace and blessings be upon him)! When will we abandon enjoining good and forbidding evil?" He replied, "When those things appear among you which had appeared among the Children of Israel: when indecency becomes prevalent among your elders, authority is given to the young, and knowledge is in the hands of the lowly."
