Abu Dawud narrated it in the same way, (b) and he said that in its chain there is Utay bin Damrah; and this hadith is ma'lul (defective) because of al-Thawri's narration of it from al-Hasan: part of it is not marfu' (attributed to the Prophet), and the remaining part, from Yunus bin Ubayd, is also not marfu'. Wallahu a'lam (Allah knows best).
