Who is a Youth?

Imam Sadiq (a.s.) once asked the students and companions who had gathered around him:

“Who is a ‘youth?”

A person answered, “Someone who is young in age.”

The Imam (a.s.) said, “Despite the old age of the People of the Cave, on account of the faith which they possessed, God has referred to them as ‘youths’.  In verse 10 of the chapter al-Kahf, He says: When the youths sought refuge in the cave. 

He then continued, “Whoever believes in God and observes piety is a youth.”
