[Hasan] Tabarani narrated it in Al-Awsat, 223/1, no. 335, from the hadith of Ibn Wahb, with this wording, and in it, "Yazid bin Abdullah Muzani, from his father," which is correct. Its chain is daif due to the obscurity of Yazid, but there is a corroborating narration for it in Ibn Hibban, no. 1057, whose chain is sahih, and it has other corroborating narrations in Abu Dawud and elsewhere.
