What the Commander of the Faithful عليه السلام Informed Regarding the Occurrence of the Occultation

حدثنا علي بن أحمد بن موسى رضي الله عنه قال حدثنا محمد بن جعفر الكوفي عن عبد الله بن موسى الروياني‌ عن عبد العظيم بن عبد الله الحسني عن محمد بن علي الرضا عن أبيه عن آبائه عن أمير المؤمنين ع‌ بهذا الحديث مثله سواء. Narrated to us Muhammad bin Ahmad Shaibani رضي الله عنه: Narrated to us Muhammad bin Ja’far Kufi: Narrated to us Sahl bin Ziyad Adami: Narrated to us Abdul Azeem bin Abdullah Hasani رضي الله عنه from Muhammad bin Ali bin Musa bin Ja’far bin Muhammad bin Ali bin Husain bin Ali ibn Abi Talib عليه السلام from his father from his ancestors from Amirul Momineen عليه السلام that he said: “For our Qaim there is an occultation, which shall be prolonged. As if I can see the Shias resembling quadrupeds searching for pasture but being unable to find it. Know that, whosoever from them remains firm on his religion and whose heart is not hardened due to the prolonging of occultation, then he shall be with us in our rank on the Day of Judgment. Then he said: When our Qaim arises, he would not have the allegiance of anyone upon his neck, therefore his birth shall be secret and he himself shall be in occultation.” 
Narrated to us Ali bin Ahmad bin Musa رضي الله عنه: Narrated to us Muhammad bin Ja’far Kufi from Abdullah bin Musa Ruyani from Abdul Azeem bin Abdullah Hasani from Muhammad bin Ali al-Ridha from his father from Amirul Momineen عليه السلام exactly the same above tradition.
