Imam Ja'far Sadiq (a.
Imam Ja'far Sadiq (a.s.) in his eldest son, others being Abdullah, Ali, Zaid, Ubaidullah and Ibrahim. Imamat and successorship is in Abu Abdullah Ja'far Sadiq (a.s.). Imam Ja'far as Sadiq (a.s.) The greatness and preciousness of this Imam is beyond the power of the tongue and the pen to describe.
His high rank of knowledge can be imagined from the fact that Jabir Ibn Hayyan Sufi, who was one of his brilliant students, has described his sciences both orally and with pen extremely and written five hundred articles and treatises. Just see that only one of the Imam's students is such a big scholar.
Then what a big collection it would become if the capabilities of all of companions and followers are counted together: Ja'far Sadiq, besides being the Imam of his time, was also an ocean of religious sciences and fountainhead of Quranic knowledge.
Abdullah bin Abbas said, "Knowledge has been divided into ten parts and nine of them are exclusively with the Amirul Mo-mineen (a.s.) and the remaining one part is divided among all the other people." Now we say that the knowledge of Amirul Mo-mineen was bequeathed to the successive Imams till it reached Imam Ja'far as-Sadiq (a.s.) and by this time it had expanded greatly and all of it was in the possession of Imam Ja'far Sadiq (a.s.).
Shaikh Abu Abdur Rahman as Sullami says in Tabaqaat al Mashaayekh: "Indeed Imam Ja'far as Sadiq (a.s.) surpassed all his contemporaries. His religious knowledge was profound, his piety absolute, his control on the sensual desires complete and his manners in wisdom perfect." The leader of Sufis and the Shaykh of Tareeqat, Baayazeed Bastami states, 'I have served ninety-nine teachers fully.
Yet had I not seen Imam Ja'far Sadiq, I would have died devoid of faith.' Just imagine the rank of this Imam from this statement. Allamah Dameeri mentions in Hayat al Haivaan, "Abu Hanifa Noman bin Thabit says, 'Once I went with Rabee to Imam Ja'far. He asked me, 'Do you follow conjecture (qiyaas)?' I replied, 'Yes'.
Imam retorted, 'Do not base your verdicts on conjecture because the first one to follow conjecture was Iblees (the devil)." Abu Hanifa says, "The Imam asked me some questions but I could not give reply to any of them. So he himself explained the problems and said, 'in your head there are four kinds of liquid; one in the mouth, second in nose, third in the ear and fourth in the eye.
