The Quran has spoken of the wrongs of the sons of Yaqub to their brother Yusuf and how they threw him into the well and sold him at a very insignificant price. And they were sons of the prophet, and some believe they were prophets. If they can perpetrate such a grave error against their brother, how Ja’far Ibn Ali cannot utter denials about his nephew in greed of worldly pleasures? Who can consider this impossible, but an obdurate opponent?
