[-/1] الكافي: محمد بن عبدالله ومحمد بن يحيى جميعا، عن عبدالله بن جعفر الحميري قال: اجتمعت أنا والشيخ أبوعمرو رحمه الله عند أحمد بن إسحاق فغمزني أحمد بن إسحاق أن أسأله عن الخلف فقلت له: يا أبا عمرو إني اريد أن أسألك عن شئ … وأخبرني أبوعلي أنه سأل ابا محمد عليه السلام عن مثل ذلك، فقال له: العمري وابنه ثقتان، فما أديا إليك عني فعني يؤديان وما قالا لك فعني يقولان، فاسمع لهما وأطعمها فإنهما الثقتان المأمونان …
1. [1/-] al-Kafi: Muhammad b. Abdallah and Muhammad b. Yahya from Abdallah b. Ja’far al-Himyari who said: We gathered – myself and the Shaykh Abu Amr [al-Amri] رحمه الله at Ahmad bin Ishaq’s place. Ahmad b. Ishaq gestured at me to ask him [al-Amri] about the Successor [al-Mahdi] so I said to him: O Aba Amr – I want to ask you something … Abu Ali [Ahmad b. Ishaq] also informed me that he had asked Aba Muhammad [al-Hasan b. Ali al-Askari] عليه السلام about the same matter and he [the Imam] said to him: al-Amri and his son are two trustees. What they give to you on my behalf then their giving is truly on mine behalf, and what they say to you on my behalf then their saying is truly on mine behalf. Therefore listen to them and obey them, for they are both trustworthy and reliable …
[2/247] غيبة الطوسي: باسناده عن عبد الله بن جعفر قال: خرج التوقيع إلى الشيخ أبي جعفر محمد بن عثمان بن سعيد العمري قدس الله روحه في التعزية بأبيه رضي الله تعالى عنه وفيه: … أجزل الله لك الثواب وأحسن لك العزاء، رزيت ورزينا، وأوحشك فراقه وأوحشنا، فسره الله في منقلبه، كان من كمال سعادته أن رزقه الله تعالى ولدا مثلك، يخلفه من بعده، ويقوم مقامه بأمره، ويترحم عليه، وأقول الحمد الله فإن الأنفس طيبة بمكانك، وما جعله الله عز وجل فيك وعندك، وأعانك الله وقواك، وعضدك ووفقك، وكان لك وليا وحافظا، وراعيا، وكافيا
2. [2/247] Ghayba of al-Tusi: Via his chain to Abdallah b. Ja’far who said: A Tawqi [signed rescript] came out to the Shaykh Abi Ja’far Muhammad b. Uthman b. Sai’d al-Amri قدس الله روحه condoling him for the death of his father رضي الله تعالى عنه. In it was written: … May Allah amplify your reward and beautify your mourning. We grieve just as you grieve. It [his death] has left you bereft just as it has left us bereft. May Allah delight him after his return [to Him]. One aspect of the perfect felicity [he attained] is that Allah the Exalted granted him a son like you, who succeeds him after his departure, stands in his place as per his command, and supplicates for mercy for him. I say ‘All praise belongs to Allah’ for the souls are comforted due to the position you have assumed [after him] and because of what Allah Mighty and Majestic has bestowed in you and with you. May Allah support and strengthen you. May He aid you and facilitate you. May He be a Guardian over you, a Protector, a Guide and Sufficient [for you].

My last meeting with him was at the Sanctified House of Allah [Ka’ba], he was saying: ‘O Allah – fulfill for me what you promised me’. Muhammad b.
