Birth of Imam al-Mahdi (as)

On July 29, AD 869, Imam Mahdi was born amid divine light, testifying to God's oneness, prophets' prophethood, and ancestors' Imamate while bowing toward the qiblah. Angels descended to congratulate Imam Hasan, and the infant recited holy books of past prophets. Archangel Rizwan washed him, Imam Hasan transferred wilayah and recited adhan. Green birds (angels led by Gabriel) took the newborn to God's Throne, where He affirmed Mahdi's role as the last proof, promising justice through him.

Hypocrites like Ahmad bin Hilal, Hasan Sharii, Husain bin Mansur al Hallaj, and Muhammad bin Ali Shalmaghani falsely claimed deputyship due to jealousy or greed, promoting deviations and facing curses or execution.
