Ahmad 7512

Its chain of transmission is sahih. Khalaf bin Mihran Abu Rabi Adawi Basri, the imam of the masjid of Banu Adi bin Yashkur, is trustworthy. Bukhari gave his biography in Kabir 2/1/177, and quoted from Abdul-Wahid Haddad that he said, "He was trustworthy and commendable." Ibn Abu Hatim also gave his biography in 1/2/379, and reported from Abdul-Wahid, who said, "Khalaf bin Mihran informed us, and he was truthful and good."Bukhari and Ibn Abu Hatim, in these two entries, distinguished between this Khalaf and Khalaf Abu Rabi, the imam of the masjid of Saeed bin Abu Aruba, but they are one and the same person. Saeed bin Abu Aruba was from Basra and belonged to Adi, being a client of Banu Adi bin Yashkur. The masjid was attributed to him at times, and to Banu Adi at other times. This is what Hafiz affirmed decisively in Tahdhib, supporting it with the report of Baghawi from Abdullah bin Awn, who said, "Abu Ubayda Haddad narrated to us, saying, 'Khalaf bin Mihran Abu Rabi Adawi narrated to us, and he was trustworthy.'" Hafiz said, "This shows that he is one person."This Khalaf is counted among the Tabiin, for he reported a hadith from Anas and explicitly stated that he heard it from him, as will come in the Musnad 13084. In the three original manuscripts here, it occurs as Khalid bin Mihran instead of Khalaf bin Mihran, and Khalid bin Mihran is Khalid Haddan. This might have been possible, were it not that the biographical entries do not mention any report of Khalid Haddan from Abdul-Rahman bin Asamm, nor any report of Abu Ubayda Haddad from Khalid Haddan. Then certainty and clarity came, for Ibn Kathir mentioned this hadith in Jami al-Masanid wal-Sunan, a manuscript, where it reads "from Khalaf bin Mihran." So we became certain that the word "Khalid" is an old error from the copyists, found in some copies of the Musnad, not all of them, since Ibn Kathir quoted it from the Musnad correctly.Abdul-Rahman bin Asamm Abu Bakr Abdi Madaini, the muezzin of Hajjaj, was a trustworthy Tabii. He explicitly stated that he heard from Abu Hurairah, as will come at 8745, and from Anas at 12221. It is said that his father's name was Abdullah, making Asamm a nickname for his father, and he is sometimes mentioned as Abdul-Rahman Asamm, as though he were given his father's nickname. The matter here is of little consequence. Ibn Main, Thawri, and others confirmed him as trustworthy, and Muslim reported from him a single hadith from Anas in his Sahih 2:153. Ibn Abu Hatim also gave his biography in 2/2/304, and reported his confirmation of trustworthiness from Ibn Main.We have discussed the sourcing of this hadith in detail at 7138, and explained the reports of those who mentioned in it the Duha prayer, and those who mentioned instead of it ghusl on Friday, and we pointed to this there.
