Letter to his parents before his departure:

“I am…obliged to pay taxes to the [U.S.] government… This in turn will be used automatically to kill my Muslim brothers and sisters… I simply cannot sit here and let my brothers and sisters get killed, with my own hard-earned money…I cannot live under a law in which I’m afraid to speak my beliefs. I want to be ruled by the Sharia [Islamic law], the best law for all-mankind.”“Letter prosecutors say Mohammed Hamzah Khan wrote to his parents,” Chicago Tribune, November 3, 2014, http://www.chicagotribune.com/chi-letter-prosecutors-say-mohammed-hamzah-khan-wrote-to-his-parents-20141103-htmlstory.html.
