23 Years: A Study of the Prophetic Career of Mohammad is a biographical book on the life of Muhammad written by Iranian author and scholar Ali Dashti. Although completed in 1973, the book was published anonymously in Beirut, Lebanon in 1974. The book is considered banned in Iran.
Following the Iranian Revolution (1979), Dashti, then in his midâÂÂeighties, was arrested, imprisoned, and sentenced to death by Islamic Revolutionary Court for writing this critical work on Islam.
The book contains criticism of the Quran
The first part of 23 Years was serialized in issue 47 of Kaveh magazine, published in Munich in 1973. At the authorâÂÂs request, his name was not mentioned, but in that article Javad Vahabzadeh introduced the work and provided clues that allowed readers to identify the author as Ali Dashti. The serialization continued through issue 58 (June 1975), after which the book was published independently in Lebanon. The work was later translated into English by F.â¯R.â¯C. Begley. According to Houshang Moinzadeh, discussions about the bookâÂÂs content were held at Ali DashtiâÂÂs home, and Dashti sought assistance from Alinaqi Monzavi, an Islamic scholar and writer who had fled Iran for Beirut for political reasons. The book circulated widely and became a major factor in the difficulties Dashti faced during the last decade of his life. According to journalist Masÿud Behnoud, Dashti, then aged 80, was sentenced to death by the Islamic Revolutionary Court for authoring 23 Years. After the Iranian Revolution, others, including Monzavi, were also imprisoned partly in connection with this book.
In 23 Years, Ali Dashti presents a rationalist interpretation of Islamic prophecy and offers one of the most critical analyses of MuhammadâÂÂs life and message. According to Dashti, MuhammadâÂÂs experience of revelation was the voice of his own conscience rather than a supernatural event, and his prophetic mission can be explained through modern psychology and sociology. Dashti rejects the doctrine of MuhammadâÂÂs infallibility and accepts accounts such as the soâÂÂcalled âÂÂSatanic Versesâ episode. He argues that the Quran should be regarded as the book of Muhammad rather than the word of God, noting what he describes as grammatical flaws and diverse sources, which he considers expected from an illiterate man. For Dashti, the QuranâÂÂs significance lies in its impact rather than in any literary miracle, comparing its untranslatable style to the poetry of Hafez. Dashti places blame on Arab culture for what he sees as many of IslamâÂÂs problems, particularly those associated with contemporary Arab Islamism. He writes that the Arabs retained materialism, resistance to abstract thought, and rebelliousness after adopting Islam. He regards organized religion as a force that often weakens reason, though he argues there is no inherent reason it must do so. Dashti maintains that if Muhammad is understood as fully human, then his actions can be seen as responses to psychological and social conditions rather than divine directives. He asserts that Muhammad sometimes acted according to expediency rather than spiritual or moral principles, and that certain rulings and rituals from his time, such as aspects of the Hajj, have become irrelevant in the modern era. On MuhammadâÂÂs multiple marriages and their references in the Quran, Dashti writes that âÂÂevery reader of the Quran should be amazed to encounter these personal matters in the scripture and the code of ethics that is valid for all humanity at all times.âÂÂ
Dashti is a strong critic of writers who interpret events in MuhammadâÂÂs life and the Quran through miracles. Instead, he emphasizes the psychological and sociological factors that, in his view, shaped MuhammadâÂÂs effort to establish a complex religion and a state. Dashti argues that the Quran originated from MuhammadâÂÂs own creative genius rather than divine revelation. While he does not deny the existence of God, he contends that God is too transcendent to be concerned with the ProphetâÂÂs personal affairs, including those of his wives, companions, and enemies. Dashti portrays Muhammad as a man with both virtues and weaknesses, subject to strong emotions and human limitations, yet generally worthy of reverence and superior to his contemporaries. 23 Years treats the Prophet with respect and even seeks to honor him, though Dashti criticizes the growth of myths and miraculous accounts surrounding Muhammad over the centuries. He also rejects many Western misconceptions about Muhammad, particularly those from the Middle Ages.
The book is organized into several main sections:
Since the publication of 23 Years, a number of rebuttals have appeared, including Betrayal in the Report of History by Seyyed Mostafa Hosseini TabatabaâÂÂi and The Great Secret of the Prophethood by JaâÂÂfar Sobhani. Both authors raise objections to DashtiâÂÂs arguments and accuse him of misquoting and misrepresenting sources. TabatabaâÂÂi in particular criticizes Dashti for lacking a basic knowledge of Arabic, questioning how someone unfamiliar with the language could comment on the Quran. As an example, he cites DashtiâÂÂs interpretation of a verse from Surah Ash-Shu'ara (26:198), arguing that DashtiâÂÂs translation is misleading. TabatabaâÂÂiâÂÂs rebuttal is noted for its harsh tone and personal attacks, which, according to researcher Paul Sparkman, reflect elements of religious fanaticism in Iran at the time. Sparkman also observes that 23 Years contains typographical errors and minor inaccuracies that, while not central to DashtiâÂÂs thesis, have been used by critics such as TabatabaâÂÂi to challenge DashtiâÂÂs credibility. Sparkman further acknowledges that Dashti did not always provide precise citations for commentators, historians, and hadiths, even though the work remains a serious and scholarly effort.
By questioning why the capacity for evil exists in human nature, Dashti challenges the need for a divine messenger. He notes that theologians claim God did not create evil, but that humans possess a nature capable of both good and evil. Dashti asks: âÂÂWho gave these people this nature in which there is the possibility of both evil and good?â He argues that a personâÂÂs character is fixed at birth and unaffected by individual will, stating that âÂÂblack people cannot be whitened by preaching,â and concludes that prophecy is therefore unnecessary.
TabatabaâÂÂi argues that Dashti contradicts himself elsewhere in 23 Years. For example, Dashti writes: âÂÂThe miracle of Muhammad is that he did not sit idly by and resisted all the insults and persecutions, and did not turn away from any plan to impose Islam on the Arabian Peninsula, to bring the different tribes of the Arabs under one brigade, who are completely alien to supernatural affairs and who turn to the senses according to their primitive nature and have no other goal than to gain immediate benefit, except to encroach on the wishes of others. It is not made of them.âÂÂ
In his review of 23 Years, Jay Norder attributes the bookâÂÂs popularity and repeated reproduction to the controversy it provoked. He describes the work as a direct attempt to demythologize the prophethood of Muhammad and to return to early historical sources such as Ibn Ishaq and Tarikh alâÂÂTabari. Norder considers Dashti well qualified to produce such a study because of his seminary background and strong command of the Arabic language.
According to Brigitte Hoffmann, a professor of Islamic studies at the University of Bamberg, 23 Years is a wellâÂÂresearched and readable book. She notes that although it has been widely circulated in Iran, from a scholarly perspective it does not offer any new interpretation of MuhammadâÂÂs life.
In an article published in Journal of the Middle East in 1987, Hamed Elgar observed that DashtiâÂÂs approach in 23 Years was to reduce the Prophet to one of many great historical figures. Elgar points out that Dashti even compares the Prophet to Lenin, suggesting that Lenin was âÂÂmore sourâ (p. 8). Elgar writes that Dashti interprets the spread of Islam as âÂÂa response to the social conditions of Meccaâ (p. 195). According to Elgar, Dashti reduces the narrative of Muhammad and his companions to a story of âÂÂviolence and greed, or unrest and confusion.â Elgar also argues that the bookâÂÂs tone recalls older Orientalist narratives and includes sharp racial generalizations, portraying Arabs, both before and after Islam, as âÂÂwild and unintelligentâ (p. 195).
Ahmad Sadri has described 23 Years as a work containing insults toward sacred beliefs and unjust accusations against the Prophet of Islam. He interprets the limited questioning and release of Dashti after the bookâÂÂs publication as evidence of some tolerance for rational critique of Islam among Muslims. By contrast, Saÿidi Sirjani reported that Dashti suffered severe mistreatment in prison, claiming that he was tortured and even sustained a pelvic injury while incarcerated.
