Ibrahim Sulayman Muhammad Arbaysh

Ibrahim Sulayman Muhammad Arbaysh (Al-Rubaish) (born July 7, 1979 in Al Brida, Saudi Arabia) is a suspected terrorist and 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, then escaped after repatriation to Saudi Arabia in 2006, and is now reported to be AQAP's mufti.

Guantanamo detention
Al-Rubaish was captured near the Pakistan-Afghan border and transferred to Saudi Arabia on December 13, 2006.

On February 3, 2009 Saudi security officials published a new list of Saudi suspected terrorists. Al-Rubaish was one of 11 of the 85 men on this list who was a former Guantanamo captive.

AQAP's mufti
In November 2009 a research paper from the think tank The Jamestown Foundation asserted that Al-Rubaish was now a mufti for Al Qaida in the Arabian Peninsula (AQAP).

Call for assassination of Saudi royals
The paper's author Murad Batal Al-Shishani asserted that Al-Rubaish had produced an audio tape Al-Qaida had released in September attempting to justify a recent attempt to assassinate a senior member of the Saudi Royal Family. The paper asserted Al-Rubaish had published a book criticizing Shaykh Salman al-Ouda, a critic of al Qaida's attacks on September 11, 2001. 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.

Repatriation and escape
Al-Rubaish was transferred to Saudi Arabia on December 13, 2006, then escaped from custody and is now reported to be a senior figure in al-Qaeda.

Call for jihad
In early 2013 Al-Rubaish called for jihad against Americans, saying "It is my duty to spur the Muslims to kill the Americans, to get them out of the Muslims' land", also expressing hope that Sunnis would unite in a war against Shiite Iran.
