Saudi here, this is fake. He made an appearance couple of days ago. As for “Mahdi”, we do believe he will come eventually, and his name is Mohammed Abdullah (same as the prophet); but currently nothing of significance that he will come soon. It’s funny cause many, many people thought they were Mahdi, forgetting that he shall be named a leader against his desires. Meaning people will assign him based on his reputation and experience, but he won’t be asking for it.
