A federal judge on Wednesday sentenced a Phoenix man to 30 years in prison for helping to plan an Islamic-State inspired attack in Texas, a case that resulted in the first conviction of its kind won by the Justice Department.
Kareem is the second person in the USA to be convicted of charges supporting the so-called Islamic State (IS) group.
Authorities say Kareem provided the guns that two friends used to open fire outside the anti-Islam event in suburban Dallas and hosted the two Islamic State followers at his home to discuss the upcoming attack. A security guard was wounded, but no one else was injured.
Such portrayals are considered offensive by Muslims.
The original indictment said Kareem supplied the two gunmen with arms and helped them prepare for the attack.
"He knew what Mr. Simpson and Soofi meant to do", said U.S. District Judge Susan Bolton.
An attorney for Kareem could not be immediately reached to comment on the sentence on Wednesday. "I had nothing to do with this crime", Kareem told the judge.
After completing his prison time, Abdul must submit to a lifetime of supervised release.
Prosecutor Kristen Brook said Kareem talked about wanting to strap a bomb to his chest and murder non-believers, and authorities said Kareem had inquired about explosives he wanted to use to blow up the 2015 Super Bowl stadium in Arizona.
She said Kareem had expressed his desire to strap a bomb on his body to kill nonbelievers.
A controversial prophet Muhammad cartoon contest was no laughing matter to an American Islamic State supporter.
Prosecutors said Kareem had watched jihadist videos depicting violence with Simpson and Soofi, encouraged them to plot an attack to support the terrorist group and researched travel to the Middle East to join IS fighters.
Two of his friends were killed in a police shootout outside a prophet Muhammad contest in Garland, Texas, two years ago.
