Tabarani narrated it in Al-Awsat, Majma Bahrayn (519), from Ali bin Saeed, who said, Zayd bin Akhzam narrated to us, who said, Abu Dawud Tayalisi narrated to us, who said, Ibrahim bin Saad narrated to us, from Zuhri, from Amir bin Saad, from his father, who said, then he mentioned it.Haythami said in Al-Majma (1/286), "Tabarani narrated it in Al-Awsat, and its narrators are the narrators of the sahih, apart from Tabarani's teacher." Its chain of transmission is sahih, but I did not find this hadith in Musnad Abu Dawud Tayalisi, so either it fell out of it, or it is found in his other books.As for Tabarani's teacher, Ali bin Saeed, he is Ibn Bashir Razi. Maslama bin Muslim rated him trustworthy, and Ibn Yunus said, "He had good understanding, he understood and memorized well, and he was among the eminent scholars of hadith."His statement, "courtyards," is the plural of courtyard, meaning a spacious area in front of a house.
