Its isnad is sahih, and it is an abridgment of a story whose full account I have not found. Perhaps it refers to a discussion between Amr bin Dinar and Abu Shatha. The hadith was narrated by the group, as in al-Muntaqa 2467, 2468. Its meaning will come again repeatedly at 2014, 2581, 2582, 2983, 3030, 3053, 3075, 3109, 3116, 3233, 3283, 3319, 3384, 3400, 3412, 3413. It will also come from the hadith of Ibn Abbas and the hadith of Jabir at 2762.
