When Ibn Tulun went to El-Sham to put down revolts there , he left his son , El-Abbas , to run the affairs of
Egypt
and he also left to his son an assistant called , El-Wasitty . Then , the troubles and problems happened between El-Abbas and El-Wasitty when the latter refused to appoint some of El-Abbas's friends in the administration , which sparked hatred between them both . Suddenly , El Abbas declared himself as the Ruler of Egypt . Moreover , he went to North Africa and said that the Caliph appointed him Governor of North Africa .
Knowing his son's practices , Ibn Tulun sent to him asking that he abstain these actions or he would curse him after each prayer , but his son did not . So Ibn Tulun decided to send an army to arrest him and put him in prison , until he died , during the reign of his oldest brother Khumarawaih .
