Iran's Supreme Leader Mojtaba Khamenei said that divisions among Muslims served the interests of their "real enemy", urging Muslim nations, especially those in the Gulf, to unite.
The message was published on Khamenei's Telegram account for Islamic Unity Week, which marks the birthday of the Prophet Muhammad (PBUH). It called for Muslim unity, cooperation in various fields and mutual defence, saying anyone who creates divisions among Muslims, "knowingly or unknowingly," helps Islam's enemies.
It asked whether Palestinians would have been left "so helpless" if Muslims had been united. Khamenei has not been seen in public since being injured in US-Israeli airstrikes six months ago that launched the Iran war, assassinating his father and previous supreme leader, Ayatollah Ali Khamenei.
His call for unity echoes a statement he made on Friday to Iranians, when he said he had banned actions that harm social cohesion and urged authorities to avoid "discouraging statements" that weaken national and public morale.
Khamenei specifically asked Gulf Arab rulers whether "rogues without identity" would have dared to covet their lands and possessions if the peoples and governments of the Gulf had been "united under the flag of Islam."
During the present conflict, Tehran has struck US military facilities as well as other infrastructure in Gulf states, underscoring the tensions between Tehran and its Gulf neighbours. "My emphatic and repeated recommendation to the rulers of Islamic countries, especially the countries of West Asia and the Gulf, is to identify your real enemy, understand his plan and confront it," Khamenei said.
