Musab Omar Ali Al Mudwani

Al Mudwani had a writ of habeas corpus filed on his behalf. Historian Andy Worthington reported that when his petition was finally considered in December 2009, it was turned down, even though he had been a "model prisoner".

Scholars at the Brookings Institution, led by Benjamin Wittes, listed the captives still held in Guantanamo in December 2008, according to whether their detention was justified by certain common allegations:

Originally, the Bush Presidency asserted that captives apprehended in the "war on terror" were not covered by the Geneva Conventions, and could be held indefinitely, without charge, and without an open and transparent review of the justifications for their detention. In 2004, the United States Supreme Court ruled, in Rasul v. Bush, that Guantanamo captives were entitled to being informed of the allegations justifying their detention, and were entitled to try to refute them.

The United States Senate Intelligence Committee report on CIA torture listed Al Mudwani as one of the individual held in the CIA's secret network of black sites. Musab al Mudwani was apprehended by a combined force of Pakistani security officials and a CIA black site team, on September 11, 2002, the anniversary of al Qaeda's attack within the USA. He and five other individuals spent slightly more than a month in CIA custody at the salt pit, prior to being transferred to Guantanamo. Guantanamo analysts maintained the narrative that these six were an al Qaeda sleeper cell they called the "Karachi Six". However, that claim had been dropped by his 2016 Periodic Review Board hearing. Mudwani was transferred to Oman on January 16, 2017.

Joint Task Force Guantanamo analysts estimate Al Madoonee was born in 1980, Al-Hudaydah, Yemen.
