Tradition of Mufaddal
Author: Imam Ja'far al-Sadiq (`a)

Muhammad Ibn Sanan relates that Mufaddal Ibn Umar narrated to him thus:
"One day after the Asr prayers, I sat between the pulpit and the sepulchre of the Holy Prophet (s.a.w.), contemplating on the exalted excellences with which Allah (swt) had endowed our Lord Sayyed Muhammad Mustafa (saw) of which the generality of the Ummah had no apperception, nor that of his supreme eminence, perfect merit, and his outstanding grandeur.

While I was absorbed in such thoughts, there arrived Ibn Abi Al Auja, an atheistic pagan and took his seat within my hearing distance. A comrade of his followed him and sat attentive to him.
