Was Islam's identity and scripture a gradual political construction under Abd al-Malik rather than a fully-formed 7th-century revelation?

Abd al-Malik did play a major role in making Islam's identity visible and uniform across an expanding empire. But that is not the same as creating Islam, Muhammad's message, or the Quran two generations earlier.

Why the revisionist argument has force

The evidence should not be dismissed. Before the reforms of Abd al-Malik, surviving state coins and official inscriptions often use older Byzantine or Sasanian formulas, and they do not consistently display the words "Islam," "Muslim," or "Muhammad." The Dome of the Rock inscriptions, completed around 691 CE, give Islam a striking public voice: they affirm God's oneness, identify Jesus as God's messenger and servant, and reject the claim that God has a son. Abd al-Malik issued new coinage and promoted a common religious vocabulary during a civil war and a period of imperial centralization.

From this, critics infer that Islam was assembled as an imperial identity after Muhammad, with its scripture and theology gradually fixed by the state. This is a serious historical question. Political power clearly affected which formulas appeared on coins, buildings, and official documents.

Public coinage is not the same as religious origin

The argument becomes weaker when silence on coins is treated as evidence that a belief did not exist. Coins are government instruments, not theological confessions. Early Muslim rulers often reused the monetary designs and administrative language of the empires they had conquered. A ruler's decision to place a creed on coins tells us when that creed became official state symbolism; it does not tell us when the creed first existed.

Indeed, the Dome of the Rock text is difficult to explain as a first invention in 691. Its language is densely Quranic or closely parallel to Quranic language, and it assumes a developed argument about Jesus, revelation, and Muhammad's prophethood. Abd al-Malik may have selected and publicized these teachings, but the inscriptions look like the public use of an already formed scriptural and theological tradition.

What the Quran and early transmission evidence indicate

The Quran itself presents its message as completed during the Prophet's lifetime:

"Today I have perfected your religion for you, completed My favor upon you, and chosen Islam as your way."

Quran 5:3

Muslim historical reports describe the Quran being collected after the Prophet's death and then copied in a standard written form under Uthman, well before Abd al-Malik. The account in Sahih al-Bukhari also distinguishes collecting scattered written materials from inventing the content. Early Quran manuscripts and inscriptions, including material dated before or around Abd al-Malik's reign, provide independent evidence that substantial portions of the text circulated earlier. Manuscripts do not prove divine revelation by themselves, but they make a late seventh-century creation much less plausible.

The Quran also identifies the Prophet's role as delivering and explaining revelation, not as founding a label only later imposed by the state:

"We sent down to you the Reminder so that you may explain to people what has been revealed to them."

Quran 16:44

What this argument does and does not establish

It establishes that Abd al-Malik standardized Islam's public presentation and used religious language for political and imperial purposes. It does not establish that he composed the Quran, invented Muhammad, or created the underlying community and beliefs. The strongest historical conclusion is therefore institutional consolidation, not theological invention.
