Imamexplained that the manner of preparation lies in the "Munajat-e Sha`baniyeh".
Imam further sheds the light on the matter as following:
I have not seen any other supplication that has been said to have been recited by all the Imams, as is the case with this Sha`baniyeh Supplication. This supplication is unique in this regard; I do not recall any other one that the Imams used to recite. The purpose of this Sha`baniyeh Supplication is to prepare you and everyone for" God's Feast".
