Abu Bakr al-Humaydi (may Allah have mercy on him) said, concerning the hadith of Urwah (may Allah be pleased with him), that the Prophet (peace and blessings be upon him) gave him a dinar so that he could buy a sacrificial animal for him.
He said: Sufyan said: We heard al-Hasan bin Umarah narrate it, saying in it: "I heard Shabib say: I heard Urwah." But when I asked Shabib, he said: "I did not hear it from Urwah; the tribe narrated it to me from Urwah."
