I say: This is an exceptionally authentic chain of transmission, fully continuous through explicit statements of transmission, and it meets the criteria of al-Bukhari and Muslim. They both transmitted it, as will follow:
Al-Bukhari transmitted it (11/362/6514) by way of al-Humaydi. So too did Abu Nu'aym in al-Hilyah (10/4), and al-Baghawi in Sharh al-Sunnah (14/259/4056), by way of al-Bukhari; likewise in his Tafsir (8/518), where he said: “Its authenticity is agreed upon.”
Abu Nu'aym also transmitted it by way of Ahmad (7/310), saying: “It is sound and established.”
Al-Tirmidhi transmitted it by way of Ibn al-Mubarak (2380), and said: “A good, authentic hadith.”
Muslim transmitted it (8/211–212), as did al-Nasa'i (1/274), Ibn Hibban in his Sahih (5/42/3097), al-Hakim (1/74), Abu Nu'aym again (10/4), and al-Bayhaqi in al-Zuhd (268/695). Abu Nu'aym also said after it: “Established and authentic.”
Qatadah also corroborated him, narrating it from Anas as a report attributed directly to the Prophet, with similar wording but more complete. Regarding the family and wealth, it states: “That is his family and servants.”
It was narrated by Ibn Hibban and al-Hakim. Al-Hakim declared it authentic according to the criteria of al-Bukhari and Muslim, and al-Dhahabi concurred. Al-Hafiz al-Iraqi judged its chain of transmission sound in Takhrij al-Ihya' (3/233). Its sourcing has already been given under no. 2481, in connection with a similar hadith from al-Nu'man ibn Bashir, and al-Iraqi judged its chain of transmission sound.
