Authenticity and Scholarship

The mantle's standing rests on continuity of custody rather than on physical testing. For the tradition, it is the cloak of the Prophet, its identity guaranteed by an unbroken chain of guardianship from the Prophet's household through Cairo to Istanbul, and by the reverence of the caliphs who kept it. That is a genuine and coherent claim of provenance, and the object is undoubtedly an old textile that has been treasured for a very long time.

What scholarship cannot supply is independent confirmation that this particular cloak was worn by the Prophet. The relic has not been radiocarbon dated or otherwise scientifically examined, an intervention that would be difficult to reconcile with its sacred status, so its attribution cannot be verified or refuted by external means, and it is recorded here as "debated" for that reason: not because there is positive evidence against it, but because the identification depends wholly on tradition. It should be noted that a separate mantle relic, also called Hirka-i Serif, is preserved at the Hirka-i Serif Mosque in the Fatih district of Istanbul and is traditionally the cloak given to Uways al-Qarani; the two are sometimes conflated under the same name. The neutral summary is that the Topkapi mantle is a long-venerated relic whose attribution to the Prophet is a matter of faith and custody.
