علي بن النعمان عن ابن مسكان عن سليمان بن خالد قال: سألت أبا عبد الله عليه السلام عما يلقى صاحب القبر فقال: ان ملكين يقال لهما: منكر ونكبر يأتيان صاحب القبر فيسألانه عن رسول الله صلى الله عليه وآله فيقولان: ما تقول في هذا الرجل الذي خرج فيكم؟ فيقول: من هو فيقولان: الذي كان يقول: إنه رسول الله، أحق ذلك؟ قال: فإذا كان من أهل الشك قال: ما أدرى قال سمعت الناس يقولون فلست أدرى أحق ذلك أم كذب فيضر بأنه ضربة يسمعها أهل السماوات وأهل الأرض الا المشركين وإذا كان متيقنا فإنه لا يفزع فيقول: أعن رسول الله تسألاني؟ فيقولان أتعلم انه رسول الله؟ فيقول: اشهد أنه رسول الله حقا جاء بالهدى ودين الحق قال فيرى مقعده من الجنة ويفسح له عن قبره ثم يقولان له: نم نومة ليس فيها حلم في أطيب ما يكون النائم.
6.ʿAlī ibn al-Nuʿmān narrated from Ibn Muskān, from Sulaymān ibn Khālid who said, “I asked Abā ʿAbdillāh  about what will be faced by one who is [buried] in the grave, so he said, ‘Verily two angels who are called Munkar and Nakīr will come to the one who is in the grave and will ask him about the Messenger of Allah (ṣ) saying, “What do you have to say about this man who rose among you?” He will ask, “Who was he?” They will say, “The one who used to say that he is the Messenger of Allah. Was that true?” So if the man was one of the doubters, he will say, “I do not know. I heard the people saying [that] but I do not know whether it was the truth or a lie.” So they will strike him such a blow that it will be audible to the inhabitants of the heavens and the inhabitants of earth, except the polytheists.[1] But if he was one of those with certitude, he will not fear and will say [confidently], “Are you asking me about the Messenger of Allah?” So they will ask, “Do you know that he is the Messenger of Allah?” He will say, “I bear witness that he is the Messenger of Allah in truth. He came with guidance and the religion of truth.” Thus he will see his position in Paradise and his grave will be expanded for him. They (the two angels) will then say to him, “Sleep a slumber wherein there is no dream, in the best state of any sleeper.”’”
