The Indication in Surat Ar-Rad Verse 29 To Hazrat Mahdi (as)

Ikmaaluddin and Maniul Akhbar:  It is narrated from Muzaffar  Alawi from Ibne  Ayyashi  from  his  father  from  Ja’far  bin  Ahmad  from  Amriki  Bufikki  from Hasan bin Ali bin Fadhdhal  from Marwan  bin Muslim  from Abu Basir that Imam Ja’far Sadiq (a.s.) said:

“Tooba (Glad tidings) for the one who is attached to our Wilayat during the occultation of our Qaim [Mahdi] and his heart does not deviate after guidance. He was asked: May I be sacrificed on you, what is Tooba? He replied: A tree in Paradise growing from the house of Ali Ibne Abi Talib (a.s.) and there will not be any believer who does not have one of its branches reaching into his house and that is the meaning of the saying of Allah, the Mighty and Sublime:

“Tooba (a good final state) shall be theirs and a goodly return.” (Surah Raad 13:29)
