I heard the Messenger of Allah ﷺ say, "Allah says, 'Son of Adam, do not fail to pray four units of prayer for Me at the beginning of your day, and I will suffice you for its end.'"
سمعت رسول الله ﷺ يقول: يقول الله عز وجل: يا ابن آدم لا تعجزني من أربع ركعات في أول نهارك، أكفك آخره.
Abu Dawud (1289) narrated it from Dawud bin Rashid, who said Walid narrated to us, from Saeed bin Abdul-Aziz, from Makhul, from Kathir bin Mura, from Naeem bin Hammar, and he mentioned it. Its isnad is sahih. Walid bin Muslim used to practice concealment through harmonization, but he explicitly stated that he heard it directly in the narration of Imam Ahmad (22470), where he narrated it from Walid bin Muslim, who said, "Saeed," meaning Ibn Abdul-Aziz, "narrated to us," except that "Kathir bin Mura" has dropped out of the isnad between Makhul and Naeem bin Hammar.I did not find anyone who explicitly stated that Makhul heard from Naeem bin Hammar, while the mention of Kathir bin Mura is established in other isnads. Among them is what Imam Ahmad (22475) narrated from Abu Saeed, the freed slave of Banu Hashim, who said Muhammad bin Rashid Dimashqi narrated to us, who said Makhul narrated to us, from Kathir bin Mura Hadrami, from Naeem bin Hammar, and he mentioned the hadith. Muhammad bin Rashid Dimashqi is truthful.Imam Ahmad also narrated it through other isnads mentioning Kathir bin Mura, and likewise Ibn Hibban (2533) narrated it through another route from Sulayman bin Musa, from Makhul, from Kathir bin Mura, from Qays Juzami, from Naeem bin Hammar, inserting "Qays Juzami" between Kathir bin Mura and Naeem.Ibn Hibban (2534) also narrated it through another route from Walid bin Muslim, who said Walid bin Sulayman bin Abu Saaib narrated to us, from Busr bin Ubaydullah, from Abu Idris Khawlani, from Naeem bin Hammar Ghatafani, and he mentioned it. This isnad is sahih, and Walid bin Muslim explicitly stated that he heard it directly.As for what Ahmad (22473) narrated from Abu Mura Taifi, from the Messenger of Allah ﷺ, similarly, some scholars, relying on this narration, held that Abu Mura was a Companion. For this reason Haythami listed him separately in al-Majma (2/236) and said, "Ahmad narrated it, and its narrators are the narrators of the Sahih." But Hafiz did not affirm his companionship in al-Taqrib, saying in the biography of "Abu Mura," a teacher of Makhul, "It is said he was a Companion, and it is said the correct view is that he is Kathir bin Mura." End of quote. I say, this latter view is closer to being correct.For Imam Ahmad narrated it from Yahya bin Ishaq, who said, "Saeed bin Abdul-Aziz informed me, from Makhul, from Abu Mura Taifi, who said, 'I heard the Prophet ﷺ'," and he mentioned the hadith. It was mentioned earlier that he narrated it from Walid bin Muslim, who said, "Saeed," meaning Ibn Abdul-Aziz, "narrated to us," who said, "Makhul narrated to us," from Naeem bin Hammar (22470).Mizzi said in al-Tuhfa (288/9), after attributing the hadith of Abu Mura to Nasai in al-Kubra, that the preserved version is the hadith of Saeed bin Abdul-Aziz, from Makhul, from Kathir bin Mura, from Naeem bin Hammar, though it is also said, from Makhul, from Kathir bin Mura, from Qays Juzami, from Naeem bin Hammar. Kathir bin Mura Hadrami Himsi belongs to the second generation. Hafiz said in al-Taqrib, "Whoever counted him among the Companions was mistaken. He is trustworthy." End of quote.
