Is the hadith about the fall of seven Arab rulers before the emergence of the Awaited Mahdi authentic?

The advent of the Mahdi is established in the Sunnah and is one of the minor signs of the Hour. However, no specific time for his advent has been mentioned in the authentic hadiths. As for the fall of seven Arab rulers before the appearance of the Mahdi, no hadith has been reported from the Prophet, peace and blessings be upon him, regarding this, neither with an authentic nor a fabricated chain of narration. It is false and has no basis, and it is not permissible to attribute it to the Messenger of Allah, peace and blessings be upon him. One of the indicators of a fabricated hadith is its absence from the accredited books of Sunnah. And whoever narrates a hadith that he believes to be false is one of the liars.
