He is annoyed by the misbehaviour of some of his Qur’aan-memorization students
Question

                I am a teacher in a circle for Qur’aan memorization for youngsters between the ages of 16 and 20, but they misbehave and mess about to an extent which only Allaah knows. What is the correct way to train these youngsters in jihad and manliness?
Praise be to Allah.Perhaps one of the best 
    ways to deal with youth of this age is to teach them about heroes and 
    conquerors, tell them about their stories and their attitudes, to create 
    ambition in them. Also tell them about the reality that Muslims face, how 
    their enemies plot against them and try to distract their youth with idle 
    entertainment. Do not be too hard on them with regard to some things that 
    are natural to them at this age, such as being concerned with how they look, 
    but teach them the limits set by sharee’ah with regard to that.

     I advise you to read the book al-Muraahiqoon by Dr. 
    ‘Abd al-‘Azeez al-Nughaymishi.

     May Allaah give you strength.
