When Imam Mahdi (PBUH) will reappear he will introduce himself in the following way by standing between Hajar-e-Aswad and Maqam-e-Ibrahim : ‘O people of the world ! Be warned , I am the Qaem ’
‘O people of the world ! Know that I am the sword with which revenge will be taken .’
‘O people of the world , my grandfather Husain (PBUH) was killed while he was thirsty .’
‘O people of the world , my grandfather Husain (PBUH) was left uncovered without a shroud .’
‘O people of the world ! My grandfather Husain’s (PBUH) body was trampled (by horses) ’
