In 1998, MAJ Hasan's dad died with funeral services held at the funeral home. In May 2001, his mother died with funeral services held at the Dar Al Hijrah Islamic Center in Falls Church. See this post for the parents' obits. Nothing much in this, in and of itself - the family had found a mosque.

What is of more potential import is that Anwar al-Awlaki became the imam of that mosque in Jan 2001. He was a very young Yemeni immigrant to the US and is well educated in secular studies as well as Islamic studies. He holds a B.S. in Civil Engineering from Colorado State University, an M.A. in Education Leadership from San Diego State University and was working on a Doctorate degree in Human Resource Development at George Washington University. During his tenure as imam, two of the 9/11 conspirators were members of the congregation; and he was well acquainted with one of them in both San Diego and Virginia. After 9/11, he was investigated by the FBI, but no charges re: 9/11 or any other jihadist activities were brought against him. He then departed for Yemen, where he now lives.

Today, he issued a tribute to MAJ Hasan, Nidal Hassan Did the Right Thing, in which he explains at length why MAJ Hasan should have done exactly what he did. Imam al-Awlaki has written extensively about jihad and has summarized his views in a pamphlet, 44 Ways to Support Jihad.

As I've said, we must keep this event in perspective - and recognize that we are dealing with an American Muslim minority. That fact, al-Awlaki was forced to admit in these two paragraphs (JMM emphasis added):

The heroic act of brother Nidal also shows the dilemma of the Muslim American community. Increasingly they are being cornered into taking stances that would either make them betray Islam or betray their nation. Many amongst them are choosing the former. The Muslim organizations in America came out in a pitiful chorus condemning Nidal’s operation.

The fact that fighting against the US army is an Islamic duty today cannot be disputed. No scholar with a grain of Islamic knowledge can defy the clear cut proofs that Muslims today have the right -rather the duty- to fight against American tyranny. Nidal has killed soldiers who were about to be deployed to Iraq and Afghanistan in order to kill Muslims. The American Muslims who condemned his actions have committed treason against the Muslim Ummah and have fallen into hypocrisy.
and so it goes in the media from our enemies' side of the ledger.
