Despite his imprisonment, he still served as a spiritual leader for radical Muslims.
Abdel-Rahman spent his entire life studying Islam and was highly educated. He studied at Cairo University's School of Theology and later earned a doctorate from Al-Azhar University in Cairo
He later went to Afghanistan, where he forged a relationship with al Qaeda leader Osama bin Laden.
Bin Laden called Abdel-Rahman the inspiration for the fateful September 11 attacks which destroyed the World Trade Center.
Despite his ties to terrorism he is still revered by many in Egypt.
