Causes of delay in reappearance of the Master of the Affair

H 276 - Saad bin Abdullah has narrated from Muhammad bin Husain bin Abil Khattab from Safwan bin Yahya from Abdullah bin Muskan from Muhammad bin Ali Halabi from Abi Abdullah Imam Ja’far Sadiq عليه السلام that he said: The Messenger of Allah صلى الله عليه وعلى آله وسلم kept his prophethood concealed for five years and remained underground due to fear. He did not publicize his message, whereas Ali عليه السلام and Lady Khadija صلى الله عليه وعلى آله وسلم were present with him. After that Allah, the Mighty and the High commanded him to announce that which he had been ordered to and to publicize his messengership.
