I like this quote from the pakistani penal code
Section 295-C of the penal code reads: "Use of derogatory remark etc, in respect of the Holy Prophet, whoever by words, either spoken or written, or by visible representation, or by any imputation, innuendo, or insinuation, directly or indirectly, defiles the sacred name of the Holy Prophet Muhammad (Peace Be Upon Him) shall be punished with death, or imprisonment for life, and shall also be liable for fine."
its hard to pay a fine if you have your head cut uoff
