Ibrahim Sulayman Muhammad al-Rubaish (July 7, 1979 – April 12, 2015) was a terrorist and a senior leader of Al Qaida in the Arabian Peninsula (AQAP), who was held in extrajudicial detention in the United States's Guantanamo Bay detention camp in Cuba.

[3] When he was captured by the US army in 2001 for alleged connections to Al-Qaeda, he was a teacher in Pakistan, ultimately being released from Guantánamo in 2006, a time during which he wrote a famed poem, Ode to the Sea, which caused controversy in India when it was included in the BA second semester syllabus at Calicut University, eventually withdrawing it.

[3] In November 2009, a research paper from the think tank The Jamestown Foundation asserted that al-Rubaish was now a mufti for Al Qaeda in the Arabian Peninsula (AQAP).

It also claimed that he had released an additional audio tape in November 2009, criticizing the Saudi government's introduction of mixed sex education for children.

Al-Rubaish was transferred to Saudi Arabia on December 13, 2006, then escaped from custody and joined AQAP in Yemen, becoming a senior figure in the group.
