Whenever the Messenger of Allah ﷺ said, "Allah hears whoever praises Him," he would say, "O Allah, our Lord, to You belongs all praise, filling the heavens, filling the earth, and filling whatever else You will."Mansur said, Awn also narrated this to me from his brother Ubaydullah.
حدثنا معاوية بن عمرو قال حدثنا زائدة عن منصور عن أبي هاشم عن يحيى بن عباد أو عن أبي هاشم عن حجاج شك منصور عن سعيد بن جبير
كان رسول الله ﷺ إذا قال سمع الله لمن حمده قال اللهم ربنا لك الحمد ملء السموات وملء الأرض وملء ما شئت من شيء بعد قال وقال منصور وحدثني عون عن أخيه عبيد الله بهذا
It has two chains of transmission from Mansur. The second of them is sahih, stated definitively by Mansur bin Mutamir without any doubt, that being his hearing it from Awn from his brother Ubaydullah, meaning from Ibn Abbas.Awn is Ibn Abdullah bin Utbah bin Masud Hudhali, and he is trustworthy. Ahmad, Ibn Main, Ajli, and Nasai all considered him trustworthy. His brother Ubaydullah is a trustworthy successor, who heard from Ibn Abbas and other companions.The first chain is problematic. In my view it appears to be daif. Mansur narrated it from Abu Hashim from one of two men he was uncertain about, whether it was Yahya bin Abbad or Hajjaj, from Saeed bin Jubayr from Ibn Abbas.Mansur is Ibn Mutamir, a trustworthy and firmly reliable narrator, who would only narrate from trustworthy sources, as we said at 1835. He narrates from Saeed bin Jubayr directly, but here he narrated from him through two intermediaries. He died in the year 132, and Bukhari included his biography in Kabir, 14/1/346.Abu Hashim is Rumani, whose name was Yahya bin Dinar, though some said Yahya bin Abu Aswad. He is trustworthy, and Ahmad, Ibn Main, Abu Zura, and Nasai all considered him trustworthy. Ibn Abdul-Barr said, "They did not disagree that his name was Yahya, and they agreed unanimously that he was trustworthy." Bukhari included his biography in Kabir, 4/2/271. He died in the year 122. He narrates from Saeed bin Jubayr directly, but here he narrated from him through one of two intermediaries, Yahya bin Abbad or Hajjaj.Yahya bin Abbad bin Shayban bin Malik Ansari is trustworthy. Nasai and others considered him trustworthy, and Mujahid praised him. He belongs to the same generation as Abu Hashim Rumani. He died after the year 120, and Bukhari included his biography in Kabir, 4/2/291-292.Now, if Mansur had stated definitively in this chain that it was from Abu Hashim from Yahya bin Abbad, the chain would have been sahih. But he was uncertain about the teacher of his teacher Abu Hashim, whether it was Yahya or Hajjaj. As for Hajjaj, I do not know who he is in this chain. It is possible he is Hajjaj bin Artah or Hajjaj bin Dinar, and both of them, in my view, lived too late to have met Saeed bin Jubayr. In fact, they came after Mansur and narrated from him. It has often happened that elders narrated from younger narrators, but their narration from Saeed bin Jubayr would then be disconnected. For this reason, I consider this chain to be daif.The hadith is sahih in any case, by the second chain, through Mansur's narration from Awn, as we said earlier.It has already been mentioned with another sahih chain at 2440, through the narration of Qays bin Saad from Saeed bin Jubayr from Ibn Abbas. Muslim narrated it, 1:137-138, and Nasai, 1:162, through the route of Qays bin Saad from Ataa from Ibn Abbas. It will come again through this route at 2498. Nasai also narrated it through the route of Wahb bin Miyas Adani from Saeed bin Jubayr from Ibn Abbas. The narration of Wahb bin Miyas will come at 2505.
