Tacit and Explicit Testimony as proof of abu Ja‘far al-Thani’s (the second) عليه السلام Divine Authority over the people after abu al-Hassan al-Rida عليه السلام

2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Mu‘ammar ibn Khallad who has said the following. “I heard (abu al-Hassan) al-Rida who said something (leadership with Divine Authority) and then said, “I do not think you need what I just said. This is abu Ja‘far عليه السلام. I have placed him in my own place to assume my position. We are of the family Ahl al-Bayt whose younger ones inherit from elder everything exactly measure to measure.”
