DETROIT (Reuters) - A Nigerian man accused of trying to blow up an airliner near Detroit with an explosive hidden in his underwear has asked to be judged by the Holy Quran rather than US law, documents filed with a federal court in Michigan show. A handwritten request by Umar Farouk Abdulmutallab, 24, asks US District Judge Nancy G. Edmunds to free him from federal prison because he "believes that all Muslims should only be ruled by the law of the Holy Quran." Edmunds will rule on that motion and five others at a pretrial hearing on September 14, a spokesman for the district court said on Friday. Abdulmutallab filed the requests on Thursday.
