Mohammed Ali Hassan Al-Moayad

Sheik Mohammed Ali Hassan Al-Moayad (; May 1, 1948 – August 12, 2017) was a Yemeni cleric who was convicted in 2005 on U.S. federal charges of conspiring to provide material support and resources to Hamas and Al-Qaeda. He then pleaded guilty to conspiring to raise money for Hamas, was sentenced to time served, and deported to Yemen. and a high-ranking member of Yemen's opposition Al-Islah party. Bin Laden reportedly issued a fatwa calling for al-Moayad's death after the cleric publicly criticized him.

In 2003, Al-Moayad traveled to Germany to meet a Federal Bureau of Investigation (FBI) informant, Mohamed Alanssi, and an FBI undercover agent posing as a wealthy former Black Panther. The FBI video-recorded al-Moayad at a Frankfurt hotel promising to funnel over $2 million to Hamas. He was then arrested by German police at the request of the FBI. Al-Moayad's assistant Mohammed Mohsen Yahya Zayed was also arrested. They appealed to the Federal Constitutional Court of Germany against extradition. This appeal was rejected, as the court found that the U.S. had given Germany assurances that the suspects would not face a military court or any other special tribunal. They were therefore turned over to U.S. custody, and taken to New York City to face trial.

In 2005, al-Moayad was convicted along with Zayed of various counts of providing material support to Al Qaeda and Hamas. The judge in the case was Sterling Johnson Jr. During the trial, Mohammed Alanssi, one of the FBI informants in Germany, served as a hostile witness to the defense. The trial proceedings included viewing of the incriminating tape made by the informants.

The prosecution also presented testimony by a survivor of a 2002 bus suicide bombing in Tel Aviv. The prosecution said that this testimony was intended to show the jury that Hamas is a terrorist organization, even though the defense did not contest this. In addition, the prosecution was allowed to present testimony from Yahya Goba, a member of the Buffalo Six, despite defense objections. Goba gave testimony as to the significance of al-Moayad's name appearing on an Al-Qaeda training camp form as recommending the applicant. The form was found in Afghanistan by U.S. soldiers. Goba also described the camp's training in explosives and weapons and the visits by bin Laden. He summarized a speech bin Laden gave which talked about the importance of "performing jihad." He arrived in Yemen in August with Zayed, where they were greeted by thousands of supporters. That same day they were congratulated in person by then-President Ali Abdullah Saleh.
