Disappearance of the expected Imam

(25) Ahmad bin Muhammad bin Sa’eed narrated from Hameed bin Ziyad from al-Hasan bin Muhammad al-Hadhrami and also it was narrated by Younus bin Ya’qoob from Salim al-Mekki from Abut-Tufayl Aamir bin Wathila that Abu Ja’far bin Muhammad as-Sadiq عليه السلام had said: “The one, whom you want and expect, will rise (and set out) from Mecca. He will not rise until he sees what pleases him even if he is obliged to eat the leaves of the trees.” Is there another way clearer than the way, with which the infallible imams عليه السلام have declared and explained the matter of the disappearance to their Shia? Will one doubt the disappearance and the reappearance of al-Qa’im عليه السلام after all these clear traditions?
