Muslims believe that the coming of the Prophet Muhammad (PBUH) was not an isolated event, but part of the same divine history that included Abraham, Moses, David, and Jesus, peace be upon them all. The Qur'an explicitly says that traces of his description were known to the People of the Book:

"Those who follow the Messenger, the unlettered Prophet, whom they find written with them in the Torah and the Gospel..." Qur'an 7:157

At the same time, intellectual honesty matters. A Muslim does not need to force every biblical passage into a prediction of Islam. Some arguments are strong, some are suggestive, and some are overstated. Isaiah 21's "burden against the desert by the sea" is one such argument: intriguing, but often presented with more certainty than the evidence allows.

The argument as its proponents state it

Isaiah 21:1-10 contains an oracle concerning "the wilderness" or "desert of the sea." The passage speaks of a severe vision, mentions Elam and Media, appoints a watchman, and then describes the watchman seeing riders. In many English translations, Isaiah 21:7 refers to horsemen, riders on donkeys, and riders on camels. The vision culminates in the cry: "Fallen, fallen is Babylon; and all the carved images of her gods he has shattered to the ground" (Isaiah 21:9, wording varies by translation).

The Muslim apologetic reading usually runs as follows:

  • The "desert" and the camel suggest Arabia, since camels and desert imagery naturally call to mind the Arabs.
  • The horsemen are read as Cyrus and Darius, Persian rulers connected with Babylon's fall or subjugation.
  • The donkey rider is connected to the Messiah through Zechariah 9:9, where the king comes "humble and riding on a donkey." Christians commonly apply that verse to Jesus, peace be upon him.
  • The camel rider is then taken as a sign of the Arabian prophet or the Arab-Muslim community.
  • The final clause about Babylon's idols being shattered is said not to have been fulfilled by Cyrus, because the Cyrus Cylinder presents Cyrus as honoring Marduk and restoring local cults rather than abolishing Babylonian idolatry. Therefore, proponents argue, the true completion of Isaiah's vision occurred only with the rise of Islam, whose uncompromising monotheism shattered idols and ended the religious order of pagan empires.

Stated at its strongest, the argument is not merely, "Isaiah mentions camels, therefore Islam." Rather, it claims that Isaiah gives a sequence: earlier imperial riders take Babylon politically, the Messiah appears humbly on a donkey, and finally a desert/camel-associated people bring the decisive religious defeat of idolatry. This is then placed alongside Qur'an 7:157 as one possible remnant of biblical testimony to the Prophet Muhammad (PBUH).

Why the reading can feel persuasive

There are several reasons a thoughtful Muslim may find this reading attractive.

First, the contrast between Cyrus and Islam is real at the level of religious policy. The Cyrus Cylinder does portray Cyrus as favored by Marduk and as restoring temple worship. Whatever one's interpretation of the cylinder as royal propaganda, it certainly does not present Cyrus as an iconoclast in the Islamic sense. He conquered Babylon, but he did not abolish Babylonian polytheism.

Second, Islam did enter history with a distinctive and powerful anti-idolatrous mission. The Prophet Muhammad (PBUH) purified the Ka'bah of idols, and the Qur'an repeatedly presents tawhid - the worship of the One God alone - as the central message of all prophets. The Muslim conquests also brought large regions under a civilization whose official theology rejected idols, images of gods, and divine kingship.

Third, the donkey and camel imagery is evocative. Zechariah 9:9's donkey rider became deeply associated in Christian interpretation with the Messiah. Camels are strongly associated in biblical imagination with desert peoples, including Arabian and Ishmaelite settings. A Muslim reader may therefore see in Isaiah 21 a symbolic procession: imperial power, messianic humility, and finally the desert people of monotheism.

So the argument is not absurd. It is a possible typological reading - that is, a reading that sees a text as having patterns which later history fills out more fully. But possible is not the same as proven.

The strongest reply

The strongest reply is that Isaiah 21, in its immediate context, appears to be about Babylon's fall in Isaiah's own prophetic horizon, not a detailed chronological prediction of Cyrus, Jesus, and Islam.

Several points matter here.

1. The passage itself names Elam and Media. Isaiah 21:2 says, "Go up, O Elam; lay siege, O Media" (wording varies). This naturally points readers toward powers east of Babylon involved in its downfall. A standard reading is that the oracle concerns Babylon's fall to the Medo-Persian sphere. Even if one debates the precise historical setting, the text itself gives us local ancient Near Eastern markers before it gives us any Arabian one.

2. The riders may not be three prophetic figures. In many translations, the watchman is told to look for "riders, horsemen in pairs, riders on donkeys, riders on camels." This can be understood as a scout's signal: different kinds of mounted messengers or military units. The later report in Isaiah 21:9 often emphasizes "riders, horsemen in pairs," followed by the announcement of Babylon's fall. It is not obvious from the text that the horseman, donkey rider, and camel rider are three separate world-historical persons or communities spread across more than a thousand years.

3. Connecting Isaiah's donkey rider to Zechariah 9:9 is interpretive, not explicit. Zechariah 9:9 is indeed an important messianic text, especially in Christian reading. But Isaiah 21 does not say "Messiah," "king," or "son of David." It simply includes donkey riders among what the watchman sees. Linking that to Jesus, peace be upon him, may be theologically meaningful, but the connection is not demanded by Isaiah 21 itself.

4. "The images of her gods are shattered" need not require a later Muslim conquest. Prophetic language often describes the defeat of a city as the defeat of its gods. When Babylon falls, its idols are humiliated because they failed to save it. The phrase may be theological and poetic, not a claim that every statue in Babylon was physically destroyed at that moment. The Bible itself frequently speaks this way: the downfall of a nation exposes the impotence of what it worshipped.

5. The historical claim is more complicated than popular presentations admit. Ancient Babylonian temple religion declined long before the seventh-century Muslim conquests. Babylon as a great city had already lost its centrality over many centuries under Persian, Hellenistic, Parthian, Sasanian, and Christian influences. By the time Muslim armies entered Iraq, the famous ancient city of Babylon was not the living center of a thriving Babylonian idol cult waiting to be shattered. Muslims conquered the region, and Islam eventually transformed its religious landscape, but it is historically too simple to say that the Muslim conquest alone "finally shattered Babylon's idols" in a direct, literal sense.

6. The Cyrus-and-Darius identification is not straightforward. Cyrus captured Babylon in 539 BCE. Darius I later suppressed Babylonian revolts, but saying that Isaiah's "two horsemen" are Cyrus and Darius is an interpretive proposal, not something clearly stated in the text. A critic can fairly ask: why those two, and not simply a pair of riders representing an approaching army or messenger report?

What a fair Muslim can say

A fair Muslim presentation should therefore be careful. It should not say: "Isaiah 21 undeniably predicts the Prophet Muhammad (PBUH) and the Muslim conquest of Babylon." That overclaims the evidence.

What can be said is more modest:

  • Isaiah 21 contains imagery of desert, camels, riders, Babylon's fall, and the humiliation of idols.
  • Islam is the great historical monotheistic movement that arose from the Arabian desert and decisively opposed idolatry.
  • The Qur'an teaches that the Prophet Muhammad (PBUH) was indicated in earlier revelation, though Muslims also believe previous scriptures have not been perfectly preserved in every wording and interpretation.
  • Therefore, a Muslim may view Isaiah 21 as part of a broader pattern of biblical motifs that resonate with Islam's emergence - especially if read typologically.

But one should also say plainly:

  • Isaiah 21's immediate context most naturally concerns Babylon and the powers surrounding its ancient fall.
  • The text does not explicitly name Arabia, Ishmael, Makkah, the Prophet Muhammad (PBUH), or the Muslim community.
  • The donkey-and-camel sequence is not unambiguous proof of Jesus followed by Islam.
  • The claim that the final clause was only literally fulfilled in the seventh century is historically and exegetically debatable.

How this relates to Qur'an 7:157

Qur'an 7:157 is a foundational verse for Muslims: it tells us that the unlettered Prophet is found written in the Torah and the Gospel. That gives Muslims good reason to examine earlier scriptures for surviving signs. However, the verse does not require us to accept every proposed biblical proof. A weak argument does not become strong simply because the Qur'an affirms the general reality of earlier prophecies.

The better approach is cumulative and principled. We look at passages about a coming prophet, a universal law, light from Paran, blessings through Ishmael's line, the spread of pure monotheism among the nations, and the historical life of the Prophet Muhammad (PBUH). Some arguments will be stronger than others. Isaiah 21 may be included as a suggestive resonance, but not as a standalone demonstration.

Conclusion

Isaiah 21's vision of riders, desert imagery, Babylon's fall, and shattered idols is striking, and it is understandable why some Muslims connect it to Islam's rise from Arabia and its war against idolatry. Steelmanned, the argument has a certain symbolic force.

Yet the strongest reading of the passage in context points first to Babylon's ancient downfall, with Elam and Media explicitly in view. The proposed sequence of Cyrus, Darius, Jesus, and the Muslim conquest is possible as a typological reflection, but not proven by the text itself.

So what does it establish? Not a decisive proof. But it may serve as one modest sign within a wider cumulative case: that the final message of tawhid brought by the Prophet Muhammad (PBUH) stands in continuity with the prophetic struggle against idols, false gods, and arrogant empires.
