Abu Dawud (4876), Ahmad (1651), and Bayhaqi in al-Adab (145) all narrated it through the route of Abu Yaman, who said, Shuayb told us, who said, Abdullah bin Abu Husayn told us, who said, Nawfal bin Masahiq told us, from Saeed bin Zayd, and he related it. Its chain of transmission is sahih, and Abu Yaman is Hakam bin Nafi al-Bahrani al-Himsi, well known by his kunya, one of the narrators relied upon by the group of hadith compilers.
