Salahudheen(رحمه الله) at 36, was the leader of Egypt and the most influential person in the world. His Humbleness is even admired by Non muslims. He never bothered for the pleasures of this life and focused in the liberation of Muslim lands.
It was said that he never laughed in any situation. When confronted about this, he replied “How can I laugh when the Masjid al-Aqsa is under the control of the Crusaders?”
Those people around him say that, he was very harsh on himself, and very lenient to others, which echos the characteristics of the first four Rightly Guided Caliphs of Islam.
This is the type of character that is required to liberate Masjid Al Aqsa.
