H 403 - It is narrated from Fadhl bin Shazan from Musa bin Sadan from Abdullah bin Qasim Hadhrami from Abi Saeed Khurasani that he said: I asked Imam Ja’far Sadiq , “Why is he named as Qaim?” He said:

“Because he will rise after his name dies. He will establish a mighty enterprise. He will rise up by the command of Allah, the Glorified.”
