The Book of Occultation — al-Ṭūsī · Hadith 81 (#Ḥadīth #15)

22- عنه، عن سعد بن عبد الله، عن محمد بن عيسى بن عبيد، عن علي بن الحكم وعلي بن الحسن بن نافع، عن هارون بن خارجة قال: قال لي هارون بن سعد العجلي: قد مات إسماعيل الذي كنتم تمدون إليه أعناقكم، وجعفر شيخ كبير يموت غدا أو بعد غد فتبقون بلا إمام. فلم أدر ما أقول، فأخبرت أبا عبد الله عليه السلام بمقالته فقال: هيهات هيهات! أبى الله، والله،أن ينقطع هذا الأمر حتى ينقطع الليل والنهار. فإذا رأيته فقل له: هذا موسى بن جعفر يكبر ونزوجه، ويولد له فيكون خلفا إن شاء الله تعالى.

H 22 - It is narrated from Saad bin Abdullah from Muhammad bin Isa bin Ubaid from Ali bin Hakam and Ali bin Hasan Nafe from Harun bin Kharja that he said: Harun bin Saad Ajali said to me: Ismail, to whom you are inclined [and in whose Imamate you hope], has died. Ja’far [Imam Sadiq] is also aged and would pass away these days and you would remain without an Imam. I did not know what to reply. I mentioned this to Imam Sadiq . Imam said: Never, by Allah! The Almighty Allah would never discontinue the matter of Imamate as long as the days and nights endure. When you meet him, tell him: This Musa bin Ja’far is growing up and we will get him married and he would get a son, who would be his Caliph and successor, if Allah wills.
