Rashad Khalifa (Arabic: رشاد خليفة; November 19, 1935 – January 31, 1990) was an Egyptian-American biochemist, closely associated with the United Submitters International (USI), an organization that promotes the practice and study of Quranism.

Similarly, he believed that previous revelations of God, such as the Bible, contained contradictions due to human interference[3] (a concept known as tahrif).

However, his changing views regarding the essence of faith, recorded in his two renditions of the Quran, and declaring himself as a divine messenger who communicated with Gabriel, drew opposition from other Muslims.

[10] Similarly, he believed that previous revelations of God, such as the Bible, contained contradictions due to human interference[11] (a concept known as tahrif).

Nineteen years after the murder, on April 28, 2009, the Calgary Police Service arrested Glen Cusford Francis, a 52-year-old citizen of Trinidad and Tobago, on suspicion of having killed Rashad Khalifa.

A specialty unit of the Tucson Police Department progressed in its investigation in 2006 and in December 2008, and was able to use DNA testing on forensic evidence from the crime scene to tie Francis to the assassination.

On December 19, the jury, after a three-hour deliberation, found Glen Francis guilty of first-degree murder and sentenced him to life in prison.

[21] Prior to the Francis trial, James Williams, an alleged member of the Jamaat ul-Fuqra organization, was convicted of conspiracy in the slaying.
