These persons were called by this names because, as Al-Kishi has claimed, there is a general concurrence of opinion among the Shiites to accept it as correct which they correct, to affirm their ideas and to the companions of Imam Muhammad Baqir (A.S.), Imam Jafar As-Sadiq (A.S.) and Imam Ali Ar-Rida (A.S.) among them. We shall describe them here as Al-Kishi has done and shall not give their account according to the group they fall in lest the account might be disjointed.
Al-Kishi, who is one of the third century scholars, has given the names in his book of Rijal as given below:
Jurists from among the companions of Imam Muhammad Al-Baqir (A.S) and Imam Jafar As-Sadiq (A.S.)
There is general agreement among the Shiites to the effect that the following companions of Imam Muhammad Al-Baqir (A.S) and Imam Jafar As-Sadiq (A.S.) should be considered as correct and that they are Jurists in the real sense. According to this opinion the most accurate and efficient jurists from among the ancients were these persons:
Ma’ruf Bin Kharbudh
Abu Basir Al-Asadi
Al-Fudail Bin Yassar
Muhammad Bin Muslim At-Taiffi
According to another version, Abu Basir Al-Muradi has been mentioned in place of Abu Basir Al-Asadi. His full name was Kaith Bin Al-Bakhtari.
Jurists from among the companions of Imam Jaffar As-Sadiq (A.S.).
In addition to the six mentioned above, there is a general agreement about the following six persons to consider as correct what they correct, affirm what they say and accept them to be Jurists.
Jamil Bin Durraj;
Abdullah Ibn Maskan;
Abdullah Bin Bakir;
Hammad Bin Isa;
Hammad Bin Uthman;
Aban Bin Uthman;
It has been said that in the opinion of Abu Ishaq Al-Faqih, whose name is Tahlabah Nin Maimun that the most efficient accomplished among these six was Jamil Bin Durraj who was the youngest of the companions of Jaffar As-Sadiq (A.S.)
Jurists among the companions of Imam Musa Al-Kazim (A.S.)and Imam Ali Ar-Rida (A.S.)
All our friends have agreed upon the fact that there are six more persons, in addition to those already described above, who should be accepted as jurists and whose opinions should be affirmed. These are:
Younis Bin Abdur-Rahman;
Safwan Bin Yahya Bayya As-Sabari;
Muhammad Bin Abi Umair;
Abdullah Bin Al-Mughirah;
