“If the fifth one of the descendants of the seventh one is missed then you are to keep fast to your religion and let nothing turn you aside from it because the executor (al-Qa’im) of this task (reviving the religion) must disappear until many of those, who have believed in him, will apostate. It will be a test, by which Allah will try His people. If your fathers and grandfathers had found a religion better than this, they would have followed it.” I said: “O my master, who is the fifth of the seventh’s descendants?” He said: “O my son, your minds are smaller than to perceive this matter and your patience is weaker than to bear it. If you live until then, you will know who he is.”
