SHAFAQNA – Imam Ali (AS) said: The one who considers himself to be the leader of the people, before education anyone must correct himself; and before educating the people with speech, do it by deeds because, the one who educates and corrects himself (first) is more deserving to respect than the one who corrects and educates others [1].
