The Prophet ﷺ said, "Shall I not teach you," and Hashim said, "Shall I not guide you to a phrase from the treasure of Paradise, from beneath the Throne, 'There is no power except with Allah.' Allah says, 'My servant has submitted and surrendered.'"
حدثنا محمد بن جعفر وهاشم قالا حدثنا شعبة عن أبي بلج قال هاشم أخبرني يحيى بن أبي سليم قال سمعت عمرو بن ميمون قال سمعت
عن النبي ﷺ أنه قال ألا أعلمك قال هاشم أفلا أدلك على كلمة من كنز الجنة من تحت العرش لا قوة إلا بالله يقول أسلم عبدي واستسلم
Its isnad is sahih. Hashim is Ibn Qasim, Abu Nadr. Ahmad narrates it from two teachers, from Shubah, from Muhammad bin Jafar, and from Hashim bin Qasim, and he has kept their two narrations separate according to what each of them said.His statement, "Hashim said, Yahya bin Abu Salim informed me," means that Muhammad bin Jafar narrated it from Shubah, from Abu Balaj, using the term "an" rather than stating direct hearing, and mentioned Shubah's teacher by his kunya, while Abu Nadr Hashim bin Qasim narrated it from Shubah and said, "Yahya bin Abu Salim informed me," thereby stating it with direct audition, using Shubah's word "informed me," and mentioned Shubah's teacher by his given name, Yahya bin Abu Salim, rather than by his kunya, Abu Balaj, though he is one and the same person.So his statement, "Hashim said..." and so on, does not mean that Hashim is the one who says, "Yahya bin Abu Salim informed me." Rather, it is a report of Hashim's narration from Shubah, and it is Shubah who says that.As for Abu Balaj, his reliability was already established at 3062, along with the account of the disagreement over his father's name. We prefer Shubah's naming of him here and in his other narrations, and we add that Ibn Saad gave his biography at 2/7/60, and Ibn Abu Hatim at 153/2/4, and neither of them mentioned any disagreement over his father's name, Abu Salim.The hadith is in Jami al-Masanid wal-Sunan 7:316, taken from this passage, and its meaning will come again, at length and in brief, through various routes, from Abu Hurairah, at 8407, 8645, 8738, 9222, 10058, and 10747. Haythami mentioned it in Majma al-Zawaid, another narration longer than the narrations in the Musnad, at 10:98-99, and said, "Bazzar narrated it, at length like this, and also briefly, and the men of both are the men of the Sahih, except for Kumayl bin Ziyad, who is trustworthy."Kumayl bin Ziyad's narration will come in the Musnad, more briefly than what was mentioned, at 10747. He then mentioned the coming narration at 8407 and said, "Ahmad and Bazzar narrated it similarly, and the men of both are the men of the Sahih, except for Abu Balaj al-Kabir, who is trustworthy."He also said, "He has another hadith with Tirmidhi besides this one." By that he is referring to a hadith in Tirmidhi 4:289, of similar meaning, narrated by Makhul from Abu Hurairah. And it is as he said.Munziri mentioned the hadith found here in Targhib wa Tarhib 2:255, and attributed it to Hakim, saying that he declared it, "Sahih, with no defect." I did not find it in Mustadrak. What I found there, at 1:517, is the lengthy hadith mentioned by the author of Majma al-Zawaid, narrated by Kumayl bin Ziyad from Abu Hurairah.Tayalisi narrated it at 2494, from Shubah, and this is the narration that will come in the Musnad at 8738. Ibn Kathir mentioned in the tafsir, 5:286, the two coming narrations of the Musnad at 10058 and 8407, and Suyuti mentioned in Durr Manthur 4:223 the coming narration of the Musnad at 8407, slightly abridged, without attributing it to anything other than the Musnad.
