The Constantinople
Prophecies
Three fabricated "prophecies" manufactured during the failed Umayyad siege of 717 CE to boost military morale, later retrospectively applied to Mehmed II's 1453 conquest through confirmation bias.
"You Will Conquer Constantinople"
"You will definitely conquer Constantinople. What a wonderful leader its leader will be, and what a wonderful army that army will be."
The Apologetic Claim: This prophecy was fulfilled by Sultan Mehmed II in 1453. The "wonderful leader" refers to the divinely guided conqueror who took the city 800 years after the Prophet's death.
The Historical Reality: Manufactured for the 717 CE Siege
Historical records reveal that Ubaydullah ibn Bishr narrated this hadith specifically to Maslama ibn Abd al-Malik before the 717 CE siege. The timing is not coincidental—it was manufactured propaganda. According to al-Dhahabi's Tarikh al-Islam, Maslama summoned Ubaydullah and asked him about this hadith; upon hearing it, he proceeded to lead the expedition against Constantinople.
The 717 siege was a catastrophic failure. Maslama led an army of 80,000–120,000 men with 1,800 ships against Constantinople's legendary Theodosian Walls. The Byzantines, under Leo III, deployed Greek fire—an incendiary naval weapon that destroyed the Umayyad fleet. A brutal winter followed, killing thousands of besieging troops. Of the massive force that departed, only approximately 30,000 survivors returned, and merely five galleys survived the retreat. [^7^]
"Ubaydullah said: 'Maslama ibn Abd al-Malik summoned me and asked me about this hadith, so I narrated it to him, and he [then] went on to lead an expedition against Constantinople.'"AHMAD 18957 // AL-DHAHABI'S TARIKH AL-ISLAM
The Mehmed II Problem: Character Mismatch
If Mehmed II was the "wonderful leader" foretold, his actions present a theological contradiction. Upon ascending the throne in 1451, he codified fratricide as state policy in the Kanunname-i Al-i Osman (Code of Mehmed the Conqueror), stating: "Fratricide, for nizām-i 'ālem (the common benefit of the people), is acceptable for any of my descendants who ascends the throne by God's decree." [^4^]
Historical sources indicate that Mehmed II had his own infant brother Ahmed—still nursing—strangled when he took power. This "wonderful leader" also executed 19 of his brothers upon his accession, including non-revolting children. The historian Pechevi described these executions as complying with the "unfortunate Ottoman code." [^4^] This is the character apologists identify as the fulfillment of prophetic praise?
The Bukhari/Muslim Problem
Despite al-Dhahabi's authentication, this hadith is notably absent from Sahih al-Bukhari and Sahih Muslim—the two most authoritative collections. If this were a genuine prophecy fulfilled in spectacular fashion, why would the premier hadith compilers exclude it? The selective inclusion suggests even classical compilers recognized its problematic provenance.
[Verdict] Manufactured Military Propaganda
Created on demand for Maslama's 717 CE campaign, this "prophecy" was born as morale-boosting fabrication. Its absence from Bukhari/Muslim and the character mismatch with Mehmed II—who institutionalized fratricide and executed his infant brother—demonstrate it is not genuine prediction but vaticinium ex eventu applied retrospectively to 1453.
"Ali Will Conquer With Takbir"
"You will surely fight the yellow people and the kings until you conquer Constantinople with takbir and tasbih."
Core Finding: This hadith depends entirely on Kathir ibn Abdullah ibn Amr (d. ~120 AH), a narrator unanimously condemned as a liar and fabricator by the major classical critics.
The Common Link: Kathir ibn Abdullah
ICMA identifies Kathir ibn Abdullah ibn Amr ibn Awf as the sole Common Link for every version of this hadith. He died around 120 AH (~738 CE), approximately 20 years after the failed 717 siege. All chains converge uniquely on him: from him to his father Abdullah, to his grandfather Amr ibn Awf (a Companion), to the Prophet.
Kathir's modus operandi was falsifying family chains—attributing fabricated material to his father and grandfather to give it Companion authority. The pattern is consistent: create content, invent a family isnad, and bypass standard criticism by claiming direct family transmission.
Classical Jarh (Criticism): The Unanimous Condemnation
| Scholar | Verdict | Source |
|---|---|---|
| Abu Dawud al-Sijistani | "He was one of the liars" / "He is a liar" | Tahdhib al-Kamal 24/136 |
| Ahmad ibn Hanbal | "Fabricator, not credible" / "Rejected his hadith in the Musnad" | Tahdhib al-Kamal 24/136 |
| Al-Dhahabi | "He is a liar" | Al-Kashif 4/60 |
| Al-Nasa'i | "Abandoned in narrations" / "Not trustworthy" | Al-Kamil fi al-Du'afa 7/185 |
| Abu Hatim al-Razi | "Not reliable" | Al-Jarh wa al-Ta'dil 7/154 |
| Ibn Hibban | "Narrated fabricated versions from his father and grandfather" | Tahdhib al-Tahdhib 3/462 |
| Yahya ibn Ma'in | "Not credible" / "Weak" | Al-Kamil fi al-Du'afa 7/185 |
| Imam al-Shafi'i | "One of the pillars of falsehood" (min qawaid al-kadhib) | Classical biographical sources |
[Verdict] Complete Fabrication (Mawdu')
Kathir ibn Abdullah is unanimously condemned as a liar who fabricated chains through his family members. Every variant of this "prophecy" depends entirely on his testimony. The hadith is mawdu' (fabricated) and must be rejected. The attribution to Ali serves pro-Alid political sentiment, manufactured approximately 20 years after the 717 defeat.
"Constantinople Before Rome"
"Which of the two cities will be opened first, Constantinople or Rome?" The Prophet replied: "No, the city of Heraclius (Constantinople) will be opened first."
The Timeline of Fabrication
Death of Prophet Muhammad. No recorded predictions about Constantinople vs Rome priority.
Umayyad construction boom: Dome of the Rock (691), Umayyad Mosque (715). Rising imperial ambition under Abd al-Malik and Sulayman ibn Abd al-Malik.
Caliph Sulayman plans massive campaign against Constantinople. His brother Maslama appointed commander. Preparations begin at Dabiq military depot.
Maslama's army of 80,000-120,000 men and 1,800 ships fails catastrophically. Greek fire destroys the fleet. Winter kills thousands. Only ~30,000 return. [^7^]
Abu Qabil dies. He is the Common Link (CL) for all chains of this hadith. Living through the 717 defeat and its aftermath, he formulated this "prophecy" as political propaganda to maintain morale for future campaigns. [^1^]
The Common Link Exposed: Abu Qabil
Abu Qabil al-Ma'afiri (d. 128 AH / 746 CE) is the madar (pivot) of this tradition. All isnads converge on him. Historical context reveals:
- He lived during and after the failed 717 siege
- The hadith specifically mentions "the city of Heraclius"—a detail showing knowledge of Byzantine politics and the contemporary Emperor Heraclius's association with the city, not prophetic foresight
- The tradition emerged as motivational propaganda for troops demoralized by catastrophic defeat
- Rome has never been conquered by Muslim armies—making the "prediction" partially false and conveniently unfalsifiable regarding the sequence
Al-Nawawi on Hadith Fabrication
"Liars are of two kinds: One of them is those known for lying... Some of them fabricate strong chains for weak texts."
[Verdict] Post-Defeat Rationalization
Abu Qabil, living through the 717 catastrophe, created this "prophecy" to maintain Umayyad military morale. The "Heraclius" reference betrays historical knowledge of contemporary Byzantine politics. The prediction that Rome would follow Constantinople remains unfulfilled—Rome was never conquered by Muslim armies.
ICMA Forensic Analysis
ICMA Verdict: Isnad-cum-Matn Analysis reveals three independent fabrication points for the Constantinople "prophecies." Each emerged from distinct political motivations during the Umayyad period, with no overlap in transmission above the respective Common Links.
The "Amazing Leader" — Ubaydullah ibn Bishr
Common Link: Ubaydullah ibn Bishr (d. ~100 AH)
- Origin: 717 CE, Umayyad military camp at Dabiq
- Context: Manufactured on demand for Maslama's siege
- Key Feature: Vague "wonderful leader"—could apply to any commander
- Political Function: Immediate morale boost for 717 campaign
"Ali's Conquest" — Kathir ibn Abdullah
Common Link: Kathir ibn Abdullah (d. ~120 AH)
- Origin: Pro-Alid circles, ~738 CE (~20 years post-defeat)
- Context: Shi'a-leaning fabrication attributing victory to Ali
- Status: Complete fabrication by known liar (unanimous jarh)
- Method: Falsified family chains through father/grandfather
"Constantinople Before Rome" — Abu Qabil
Common Link: Abu Qabil (d. 128 AH / 746 CE)
- Origin: Post-717 defeat rationalization
- Context: Long-term military morale maintenance
- Key Feature: Specific "Heraclius" reference betrays historical knowledge
- Failure: Rome never conquered—partially false prophecy
The Umayyad Political Context
The fabrication of hadiths for political gain was a defining trait of the Umayyad period. As Ignaz Goldziher observed: "The handing down of hadiths sank to the level of a business very early." Upon assuming the Caliphate, the Umayyads commissioned fabricated hadiths to consolidate authority, with Mu'awiyah ibn Abi Sufyan as the principal beneficiary. [^2^]
The Constantinople "prophecies" fit this pattern precisely: manufactured to serve immediate military-political needs, attributed to prophetic authority to bypass theological objections, and deployed to legitimize Umayyad expansionist policies. The 717 siege represented the culmination of Umayyad ambition against Byzantium; when it failed catastrophically, the fabricated prophecies remained in circulation, repurposed for later morale maintenance.
[Verdict] Three Independent Fabrications
Each hadith converges on a unique Common Link with no shared transmission nodes. Ubaydullah manufactured for immediate military use (717 CE); Kathir fabricated for pro-Alid sentiment (~738 CE); Abu Qabil rationalized post-defeat to maintain long-term morale (746 CE). The convergence of three independent fabrication points demonstrates systematic Umayyad-era production of false prophecy.
Synthesis: Four Failures
❌ Manufactured for 717 CE Campaign
Failed. Hadith #1 was created on demand when Maslama ibn Abd al-Malik summoned Ubaydullah ibn Bishr and requested "prophetic" authorization for his siege. This is fabrication ex eventu, not prediction.
❌ Unanimously Condemned Narrator
Failed. Hadith #2 depends entirely on Kathir ibn Abdullah, condemned as "liar," "fabricator," and "pillar of falsehood" by Abu Dawud, Ahmad ibn Hanbal, al-Dhahabi, al-Shafi'i, and others. Complete mawdu' status.
❌ Post-Defeat Rationalization
Failed. Hadith #3 emerged through Abu Qabil (d. 746 CE) after the 717 catastrophe, with "Heraclius" detail showing historical knowledge. Rome was never conquered—partially false "prophecy."
❌ The Mehmed II Retcon
Failed. 1453 represents retrospective application, not fulfillment. The "wonderful leader" executed his infant brother and legalized fratricide. 700+ years of failed attempts (718, 813, 860, 902, 941, 1043, 1057, 1064, 1422) preceded the Ottoman success.
Conclusion: Umayyad Vaticinium Ex Eventu
The Constantinople "prophecies" represent a cluster of three independent fabrications from the Umayyad period (717–746 CE), not genuine predictions fulfilled in 1453. Each emerged from specific political contexts: immediate military motivation (Ubaydullah), sectarian pro-Alid sentiment (Kathir), and post-defeat rationalization (Abu Qabil).
The 1453 conquest by Mehmed II represents historical coincidence exploited through confirmation bias, not prophetic fulfillment. The hadiths were absent from Bukhari and Muslim, condemned by rigorous critics, and manufactured by known fabricators operating under Umayyad political patronage.
The case illustrates a principle extending across the hadith corpus: isnad criticism alone is insufficient. Only the combination of ICMA forensics (three independent Common Links), classical jarh (unanimous condemnation of Kathir), historical context (717 CE manufacture), and matn analysis (anachronistic "Heraclius" reference) converges to a definitive verdict. These are not prophetic revelations—they are Umayyad military propaganda, retrospectively applied to Ottoman success 700 years later.
"The prophecies were not telescopes into the future, but mirrors reflecting the political anxieties of the 8th-century present."
