Blameful adversaries
The first person who due to ignorance of Imam Mahdi (hgr)’s birth, denied the birth of Imam Mahdi (hgr), was Ja’afar (the Imam’s uncle)!
Ja’afar used to strongly inhibit the news of the Imam’s birth!!
Ibn-e-Hazm in the book “Al-Fasl fil-Milal…” impeached [Imam Mahdi’s (hgr)]’s birth. He wrote that Imam Mahdi’s (hgr)’s birth didn’t occur till Imam Askari (pbuh)’s martyrdom!
