Rashad Khalifa (Arabic: رشاد خليفة; November 19, 1935 – January 31, 1990) was a prominent Egyptian-American biochemist whose revolutionary religious interpretations and foundational work with the United Submitters International (USI) sparked significant theological debate and widespread controversy within the global Islamic community. Holding a PhD in biochemistry, Khalifa initially lent his expertise as a consultant for the United Nations Industrial Development Organization (UNIDO) before transitioning to focus on his unique religious insights.
The United Submitters International, founded by Khalifa, emerged as a distinct and influential offshoot of Quranist Islam. This movement fundamentally advocates for the Quran as the sole, complete, and fully detailed source of religious law and guidance, thereby consciously rejecting the authority and necessity of the Hadith (sayings, actions, and approvals attributed to Prophet Muhammad) and Sunnah (traditions and practices of the Prophet), which are central pillars of Traditionalist Islamic schools of thought. Khalifa's specific iteration of Quranism, promoted through the USI, emphasized a strict, computer-assisted adherence to what he believed was the Quran's original, unadulterated divine message.
Khalifa gained international notoriety for his highly controversial claims regarding the existence of an intricate mathematical structure embedded within the Quran, which he termed the "Quran Code" or "Code 19." He posited that this complex numerical pattern, meticulously woven around the prime number 19, served as an irrefutable divine signature within the holy text, thereby offering ultimate proof of its divine origin, preserving its integrity, and identifying any supposed interpolations. His extensive research, heavily reliant on sophisticated computer analysis, led him to assert that virtually every measurable element of the Quran – from the exact number of chapters (114, which is 19 x 6) and verses to the precise frequency of specific words and letters – was intricately interwoven with the number 19. For instance, he famously highlighted that the opening verse of the Quran, "Bismillah Al-Rahman Al-Rahim" (In the Name of God, Most Gracious, Most Merciful), consists of exactly 19 letters. Furthermore, he controversially claimed that this pervasive code mathematically revealed two specific verses (9:128-129) of the Quran as later, unauthorized interpolations, allegedly disrupting the divine mathematical pattern and signifying their non-Quranic origin.
These revolutionary and divisive teachings, particularly his outright rejection of the Hadith and Sunnah and his assertion that certain Quranic verses were inauthentic, placed him in profound theological conflict with the vast majority of Traditionalist Muslims, including both Sunni and Shia scholars, who consider the Quran inviolable in its current form and the Hadith as an indispensable interpretive source for Islamic law and practice. Khalifa further escalated this theological contention by claiming to be God's "Messenger of the Covenant," a title he derived from his interpretation of the Quranic code. This claim, which implied a unique prophetic-like status for himself in a post-Prophet Muhammad era, intensified accusations of apostasy and heresy from mainstream Islamic authorities, making him a deeply polarizing figure.
Tragically, Rashad Khalifa's life was cut short on January 31, 1990, when he was assassinated at the mosque he had founded in Tucson, Arizona, which served as the headquarters for the United Submitters International. His violent death is widely believed to be a direct and tragic consequence of the intense theological disagreements and profound opposition his highly controversial teachings had generated within various segments of the global Muslim community. Despite his assassination, the United Submitters International continues to actively promote his interpretations and the concept of Code 19, maintaining a notable, albeit niche, presence among those who follow his specific brand of Quranism.
