al-Qaeda

al-Qaeda appears in Guantánamo Diary as a movement whose meaning changes across the years covered by the book: first, an organization Slahi joined while fighting the communist government in Afghanistan; later, a network whose members and acquaintances became the basis for a prolonged U.S. detention case. The decisive tension is between his account that he left when the Afghan conflict turned inward and the government’s later argument that his oath and intermittent associations showed he remained part of the organization.

Formation of Slahi’s connection

In early 1991, while studying electrical engineering in Germany, Slahi interrupted his education to join the insurgency against Afghanistan’s communist-led government. The book situates this decision within a period when young men could travel openly to participate and when the cause was actively supported by Western countries, including the United States. To prepare, Slahi spent seven weeks at the al-Farouq training camp near Khost. The camp was operated by al-Qaeda, and Slahi swore an oath of loyalty to the organization. He received training in light arms and mortars; at a later hearing, he recalled that the weapons were mostly Soviet-made and that the mortar shells were made in the U.S.A.

Slahi returned to his studies, then went back to Afghanistan in early 1992 as the communist government approached collapse. He joined a unit commanded by Jalaluddin Haqqani during the siege of Gardez, which fell three weeks after Slahi arrived. But victory over the communists did not bring the united cause he had expected. As factions of the mujahideen began fighting among themselves for power, he decided to return to Germany rather than fight other Muslims. In his account, his purpose had been to oppose the communist authorities’ restrictions on religious practice, not to take part in an internal struggle for political office.

Departure and continued personal ties

Slahi described the Afghan factional fighting as the end of his commitment to al-Qaeda. He distinguished the organization he had joined in 1991, when its stated struggle was against the communists, from its later direction. He said that by the mid-1990s al-Qaeda wanted to wage jihad against America, a course he did not join. His position was that this later conflict belonged to the organization and that he had become independent of it. This distinction—an early oath followed by a claimed withdrawal—would later become central to arguments about whether past membership established continuing allegiance.

Leaving the organization did not mean that Slahi broke off every personal relationship connected to it. Back in Germany, he remained friends with, or in contact with, companions from Afghanistan, some of whom retained al-Qaeda ties. He also had family connections to Mahfouz Ould al-Walid, known as Abu Hafs: Abu Hafs was both a distant cousin and Slahi’s brother-in-law through marriage. He held a seat on al-Qaeda’s Shura Council and served as one of Osama bin Laden’s senior theological advisers. The book describes occasional telephone contact between the cousins while Slahi lived in Germany. A call from Abu Hafs, placed using bin Laden’s satellite phone, attracted the attention of German intelligence in 1999. On two occasions, Slahi also helped transfer $4,000 to Abu Hafs’s family in Mauritania around Ramadan.

These details support a picture of overlapping kinship, friendship, and assistance, but they do not by themselves establish that Slahi was an active member at the time of his later detention. That distinction is especially important because the government’s case eventually relied heavily on the same contacts that Slahi presented as sporadic and bounded. Judge James Robertson later considered whether those relationships showed continued membership, while observing that their limited frequency could also fit Slahi’s effort to avoid close ties without making himself an enemy of people he knew.

The organization as a detention rationale

The government’s account of Slahi’s connection to al-Qaeda changed in emphasis over time. In 2002, when he arrived at Guantánamo Bay detention camp, available reporting described the camp’s population as lacking major al-Qaeda leaders. The book gives no indication that Slahi was then regarded as an especially high-value detainee. A year later, however, a connection to the September 11 hijackers surfaced through the interrogation of Ramzi bin al-Shibh. Slahi acknowledged that bin al-Shibh had stayed at his home in 1999 and recounted the allegation that he had advised him to travel to Afghanistan for training. Bin al-Shibh was reported to have identified Slahi as an al-Qaeda operative and attributed a crucial role to him in his own involvement in the attacks. These were allegations reported through interrogation and intelligence, not a finding that Slahi had planned or aided the attacks.

The distinction became explicit in later legal proceedings. When Slahi’s habeas petition was heard in 2009, the government did not argue that he was a major al-Qaeda figure or that he had participated in the organization’s plans or attacks. Instead, it argued that he was part of al-Qaeda because he had sworn an oath, associated with its members, hosted people described as its leaders, and referred aspiring jihadists to a known operative. At that time, the district court considered whether a detainee was an active member when taken into custody. The government relied on Slahi’s early oath and his later interactions with Abu Hafs and other acquaintances; the court considered whether those interactions amounted to continuing membership, rather than treating every contact as proof of it.

The government also initially advanced the theory that Slahi was detainable because he had aided the September 11 attacks. It later abandoned that argument, acknowledging that he probably did not know about the attacks. The appeals court likewise emphasized that he had not been criminally indicted for material support to al-Qaeda and that the government was not seeking detention on the basis that he aided the attacks. Its revised legal standard nevertheless allowed the government to argue that associations with active members made continued membership more likely, keeping those older relationships relevant to whether Slahi could be detained.

A contested label and its consequences

In the book, al-Qaeda’s importance therefore extends beyond the organization’s actions to the way its name structures the government’s case. The same biography could be read as a sequence of departures and limited contacts or assembled into a pattern of continuing association: the oath at al-Farouq, the return to Afghanistan, relationships maintained in Germany, family ties to Abu Hafs, and Slahi’s hosting of visitors. The legal dispute turned on how these separate facts should be joined and what they could establish about his status years later.

That contested interpretation also appears in the wider climate of detention. An interrogator expressed the belief that every Arab was a terrorist until proven innocent, while Slahi argued that people should first identify terrorists rather than harm everyone in terrorism’s name. The point is not that this statement defines al-Qaeda, but that suspicion of the organization could expand into a generalized assumption about Arab detainees. The book’s account of the government’s initial claim that Guantánamo had gathered dangerous adversaries, followed by its recognition that many detainees were non-combatants, underscores the consequences of treating the label as a substitute for individualized proof.

Al-Qaeda thus occupies two distinct positions in Slahi’s story: a real organization to which he says he pledged allegiance and from which he says he withdrew, and a legal category through which the U.S. government sought to explain his prolonged detention. The unresolved gap between those positions—between an acknowledged past oath, disputed later associations, and the abandoned claim of involvement in September 11—makes the organization central to the book’s examination of how political affiliation, personal ties, and evidence become grounds for confinement.
