It is narrated from Sayyiduna Hani (may Allah be pleased with him) that when he came to the Messenger of Allah (peace and blessings be upon him) as part of a delegation, he said: "O Messenger of Allah! What thing makes Paradise obligatory?" He (peace and blessings be upon him) said: "Hold fast to excellence in speech and to feeding people." This is a sound hadith in which there is no hidden defect ('illah), and the two of them (Imam Bukhari and Muslim) did not record it. The defect in their view is that Hani bin Yazid has no narrator other than his son Shurayh. However, I have already stated the condition at the beginning of this book: when a well-known Companion has only one well-known Tabi'i narrating from him, we will use him as evidence and declare his hadith sahih, because it is sahih on the condition of both of them. Imam Bukhari used as evidence the narrations of Qays bin Abi Hazim from Mirdas al-Aslami and of Qays from Adi bin Amirah, while they have no narrator other than Qays. Likewise, Imam Muslim used as evidence the narrations of Abu Malik al-Ashja'i and of Majza'ah bin Zahir, each from his own father. Therefore, according to their own principle, using the narration of Shurayh bin Hani from his father as evidence becomes binding, because al-Miqdam and his father Shurayh are among the senior Tabi'in, and Hani bin Yazid came to the Messenger of Allah (peace and blessings be upon him) with a delegation.
