It is narrated from Sayyiduna al-Walid bin Uqbah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Some people of Paradise will look down upon some people of the Fire and ask (them): 'Why did you enter the Fire? By Allah, we entered Paradise only through the knowledge we learned from you.' They will reply: 'We used to say (good things) but did not act upon them ourselves.'"
No one narrated this hadith from Isma'il bin Abi Khalid (may Allah have mercy on him) except Abu Bakr al-Dahiri (may Allah have mercy on him), and Zuhayr (may Allah have mercy on him) is alone in narrating it from him.
