Sound question on shia Mahdi

Shias claim that this world can’t stay without hujjah, and they sometimes give as an example that prophet (sallalahu alaihi wa ala alihi wa sallam), when he was leaving Madina, always put someone instead of him.

QUESTION: Did you Mahdi followed to sunnah of his forefather (sallalahu alaihi wa ala alihi wa sallam) and put someone instead of himself, when he left world for great ghaybah?


1) Yes he did. And explanation.

2) No he didn’t. And explanation.
