Ahmad (7027) narrated it from Yaqub and Saad, who said, our father narrated to us, from Ibn Ishaq, meaning Muhammad, Abdul-Rahman bin Harith narrated to me, from Amr bin Shuayb, from his father, from his grandfather, and he mentioned it. Its isnad is hasan because of Muhammad bin Ishaq, since he explicitly stated that he was narrating directly, and also because he was corroborated. This corroboration is what Ahmad (7012) narrated through another route, from Abdul-Rahman bin Zinad, from Abdul-Rahman bin Harith bin Abdullah bin Ayyash bin Abu Rabia, with his isnad, in a lengthy context, which includes, "Indeed, there is no shighar in Islam."
