The Book of Occultation — al-Ṭūsī · Hadith 101 (#Ḥadīth #18)

41- قال وحدثني أحمد بن الحسن قال حدثني يحيى بن إسحاق العلوي عن أبيه قال دخلت على أبي عبد الله عليه السلام فسألته عن صاحب هذا الأمر من بعده، قال: صاحب البهمة. وأبو الحسن في ناحيـة الدار ومعه عناق مكية ويقول لهـا: اسجدي لله الذي خلقك. ثم قال: أما إنه الذي يملأها قسطاً وعدلاً كما ملئت ظلما وجورا.

H 41 - Narrated to me Ahmad bin Hasan that: Narrated to me Yahya bin Ishaq Alawi from his father that: We came to Imam Ja’far Sadiq and inquired from him about his successor. Imam said: The same who is with that animal. At that moment Abul Hasan Imam Kadhim was in a section of the house with a lamb and telling it: Prostrate for the God, Who has created you. After that, Imam Ja’far Sadiq said: Know that he is the one who would fill the earth with justice and equity, just as it would be fraught with injustice and oppression.
