Chapter 11 | Evidence of the Imamate of Imam Musa Kadhim and refutation of Waqifiya
51- قال: وأخبرني إبراهيم بن محمد بن حمران وحمران والهيثم بن واقد الجزري عن عبد الله الأرجاني قال: كنت عند أبي عبد الله عليه السلام إذ دخل عليه العبد الصالح عليه السلام فقال: يا أحمد افعل كذا. فقلت: جعلت فداك،اسمه فلان. فقال: بل اسمه أحمد ومحمد. ثم قال لي: يا عبد الله إن صاحب هذا الأمر يؤخذ فيحبس فيطول حبسه فإذا هموا به دعا باسم الله الأعظم فأفلته من أيديهم.
H 51 - Narrated to me Ibrahim bin Muhammad bin Humran and Humran Haitham bin Waqid Jazari from Abdullah Rajani that he said: I was with Imam Ja’far Sadiq when Abde Salih, Imam Kadhim entered and Imam Ja’far Sadiq said: Ahmad, do that. I said: May I be your ransom, his name is so and so (Musa)! He replied: On the contrary, his name is Ahmad and Muhammad. After that he said: O Abdullah, indeed the master of the affair will be arrested and imprisoned for a long time. Thus when they decide to eliminate him, he would pray to Allah, the Mighty and Sublime to release him from their clutches.
