SHAFAQNA – Imam Ali (AS) said: Be aware that the one from us (Imam Mahdi (AJ)) who will face future mischief, will tread with a bright light and will behave in the same way and tradition of the Prophet (PBUH) and Imams (AS) in order to undo the knots, to set free the slaves and imprisoned nations, scatter the oppressors and misled groups as well as gather all justice seeking people.
Imam Mahdi (AJ) will live for a very long time hidden from people so that trail finders cannot find his trail even though they try very hard to find the effects or signs of him. Then a group will get ready to destroy the sedition and they will be polished like swords, their eyes will illuminate with the Quran and the sound of the Quran are in their ears, and in the mornings and the nights they will drink from bowls of wisdom [1].
