The Book of Occultation — al-Ṭūsī · Hadith 112 (#Ḥadīth #29)

52- قال: وروى بعض أصحابنا عن أبي محمد البزاز قال: حدثنا عمرو بن منهال القماط عن حديد الساباطي عن أبي عبد الله عليه السلام قال: إن لأبي الحسن عليه السلام غيبتين؛ إحداهما تقل والأخرى تطول،حتى يجيئكم من يزعم أنه مات وصلى عليه ودفنه ونفض تراب القبر من يده. فهو في ذلك كاذب؛ ليس يموت وصي حتى يقيم وصيا، ولا يلي الوصي إلا الوصي،فإن وليه غير وصي عمي.

H 52 - Some of our scholars have narrated from Abu Muhammad Bazzaz that he said: Narrated to us Amr bin Minhal Qummat from Hadid Sabati from Imam Ja’far Sadiq that he said: Abul Hasan, Kadhim will have two occultations: one would be short and the other lengthy. Till the time a person will come to you and report that he has participated in his funeral etc., in that case that person is definitely a liar. My successor will not die till he has fulfilled the duty of his successorship, and the matters of the successor are not taken up, except by the successor and if anyone else performed this duty, he would lose his eyesight.
