Sheikh Omar Abdel-Rahman, , commonly known in the United States as "The Blind Sheikh", was a blind Egyptian Islamist militant who served a life sentence at the Federal Medical Center, Butner near Butner, North Carolina, United States. Formerly a resident of New York City, Abdel-Rahman and nine others were convicted of seditious conspiracy in 1995. His prosecution grew out of investigations of the 1993 World Trade Center bombing.

Sayyid Ibrahim Husayn Qutb was an Egyptian Islamic scholar, revolutionary, poet, and a leading member of the Egyptian Muslim Brotherhood in the 1950s and 1960s. In 1966, he was convicted of plotting the assassination of Egyptian President Gamal Abdel Nasser and was executed by hanging. He is considered as "the Father of Salafi jihadism", the religio-political doctrine that underpins the ideological roots of global jihadist organisations such as al-Qaeda and ISIL.
