[Machine] "The Prophet ﷺ prayed the morning prayer and then said, 'I bear witness to so-and-so.' Abu Ishaq reported this from a sheikh whom he had never heard anything else from, except for this hadith. And that sheikh was Abdullah bin Abi Basir. Shu'bah also reported from Abu Ishaq that he heard it from his father, and Abu Ishaq heard it from Al-Aizar bin Hurayth who said, 'I only consider a hadith authentic.' And I heard Abu Bakr bin Ishaq, the jurist, saying, 'I heard Ibrahim bin Ishaq Al-Harbi saying, "I heard Ali bin Al-Madini saying that Abu Ishaq heard from Abdullah bin Abi Basir and his father Abi Basir." Abu Bakr bin Ishaq said, "I heard Abdullah bin Muhammad Al-Madini saying, 'I heard Muhammad bin Yahya saying that the narration of Yahya bin Sa'id and Khalid bin Al-Harith from Shu'bah and the saying of Abu Al-Ahwas from Abu Ishaq, from Al-Aizar bin Hurayth are all preserved.' The validity of these narrations has been confirmed by the statements of Hadith scholars. As for the two sheikhs, they did not present any opposition to this.'"
