Khashoggi fiancee calls for this Friday mass absentee funeral prayers across Muslim world

The Turkish fiancee of Jamal Khashoggi has called on Muslims to perform an absentee funeral prayer for the murdered Saudi journalist.

Hatice Cengiz took to Twitter on Sunday to make the appeal amid reports Khashoggi's body was dissolved in acid after his killing in the Saudi consulate in Istanbul.

"I call on the Muslim masses to perform the absentee funeral prayer for the soul of Jamal Khashoggi in all mosques in the Islamic world and in the Prophet's Mosque in Medina after the upcoming Friday prayers on November 16," Cengiz said.

The absentee prayer (Salat al-Ghaib) is performed for a dead Muslim when their body is missing.

Cengiz's comments come after she expressed "shock and sadness" last week over reports that Khashoggi's killers poured the remains of the insider-turned-critic of Riyadh down the drain after dissolving him in acid.

She said that Khashoggi's killers have deprived his loved ones of conducting funeral prayers and burying him in Medina, Saudi Arabia, as he had wished.

On Sunday, a Turkish journalist revealed the last words of Khashoggi that were reportedly documented in an unpublished audio recording.

"I'm suffocating... take this bag off my head, I'm claustrophobic," Nazif Karaman said Khashoggi's final words were inside the Saudi consulate in Istanbul.

Khashoggi was last seen entering the consulate on 2 October to obtain documents for his forthcoming marriage to Cengiz.

After repeated denials, Saudi Arabia finally admitted the 59-year-old had been murdered at the mission in a "rogue" operation.

However, Turkish leader Tayyip Erdogan has accused the "highest levels" of the Saudi government of ordering the hit. Some officials have pointed the finger at the all-powerful Crown Prince Mohammed bin Salman.
