What is the authenticity of the hadith: "The Fitna of Syria, its beginning is the play of boys..."?

This narration is found in Ma'mar ibn Rashid's Jami', and it contains an unknown narrator. Its wording is: Abdur-Razzaq informed us, from Ma'mar, from a man, from Ibn al-Musayyab, who said: "There will be a tribulation in Al-Sham, its beginning like the play of children; it will flare up from one side and subside from another, and it will not cease until a caller proclaims: 'Indeed, the Amir is so-and-so.'" He said: Then Ibn al-Musayyab would rub his hands together until they trembled, and then he would say: "That is truly the Amir, that is truly the Amir." So, it is a weak narration.
