١١ - حدثنا محمد بن يعقوب الكليني - رحمه الله - عن علي بن محمد، عن الحسن بن عيسى بن محمد بن علي بن جعفر، عن أبيه، عن جده، عن علي بن جعفر، عن أخيه موسى بن جعفر أنه قال: إذا فُقد الخامسُ من ولد السابع فاللهَ اللهَ في أديانكم؛ لا يُزيلنّكم عنها، فإنه لا بُدّ لصاحب هذا الأمر من غيبةٍ حتى يرجع عن هذا الأمر مَن كان يقول به، إنما هي محنة من الله يمتحن الله بها خلقَه، ولو علم آباؤكم وأجدادكم ديناً أصحّ من هذا الدين لأتّبعوه. (قال) قلت: يا سيدي، مَن الخامس من ولد السابع؟ فقال: يا بنيّ، عقولُكم تصغر عن هذا وأحلامُكم تضيق عن حمله، ولكن إنْ تعيشوا فسوف تدرِكونه.
(11) Muhammad bin Ya’qoob al-Kulayni narrated from Ali bin Muhammad from al-Hasan bin Eessa bin Muhammad bin Ali bin Ja’far from his father from his grandfather from Ali bin Ja’far that his brother Imam Musa bin Ja’far (al-Kadhim)  had said: “If the fifth one of the descendants of the seventh one is missed then you are to keep fast to your religion and let nothing turn you aside from it because the executor (al-Qa’im) of this task (reviving the religion) must disappear until many of those, who have believed in him, will apostate. It will be a test, by which Allah will try His people. If your fathers and grandfathers had found a religion better than this, they would have followed it.” I said: “O my master, who is the fifth of the seventh’s descendants?” He said: “O my son, your minds are smaller than to perceive this matter and your patience is weaker than to bear it. If you live until then, you will know who he is.”
