Muhammad Qutb
There he edited and published Sayyid's books and taught as a professor of Islamic Studies at (according to different sources) either Mecca's Umm al-Qura University, and/or King Abdulaziz University in Jeddah, and that either Osama bin Laden or Ayman al-Zawahiri (al Qaeda's #2 and leading theorist), was a student. Osama bin Laden recommended "Sheikh Muhammad Qutb's" book, ""Concepts that Should be Corrected" in a 2004 videotape. According to Lawrence Wright, who interviewed Muhammad Qutb and a close friend in college of bin Laden's, Mohammed Jamal Khalifa, bin Laden "usually attended" Muhammad Qutb's weekly public lectures at King Abdul-Aziz University.
