ADNAN OKTAR:Let me state that these are all said by Hazrat Ali (ra). That is from the original source, from my grandfather. He says "Mahdi (pbuh) is the biggest shelter among you". That is to say people will resort to him. "He is the one with the biggest knowledge among you." He will have a knowledge given by Allah, he will get his knowledge from Allah. That is because as you know Mahdi(pbuh) is illiterate, insha'Allah.  And he says "May Allah make his appearance means for the removal of sadness." See that Hazrat Ali(r.a) prays for this. The sadness will disappear. He will put away sadness from people. "Let the disorganization of the ummah be gathered through him." He prays for the scattered ummah to be gathered through him. "If Allah renders you successful, run for his obeisance and never give up on him." He says if you go by him they would try to make you give up on him, they would cause dissension and defame him. Never give up on him he says. "If you succeed and reach him and thus find the right way." That means if you go to the Mahdi(pbuh) and Allah leads you to right path, "Never give up on him," he says. And Hazrat Ali(r.a) pointing to his chest says "How much I would want to see him". He points his chest and says "I would want to see him very much" and he says "ah, How much I would want to see him". Pointing to his chest, he shows this as a hardship, as a spiritual hardship, this is a test for Hazrat Ali(r.a) right? Of course he points at his chest and says "how much I would want to see him". Insha’Allah.
