Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "On the Day of Resurrection, the mu'adhdhins will be the people with the longest necks." Then the narrator mentioned the full hadith.
Al-Tabarani recorded it in al-Awsat; its chain contains a narrator, Abu al-Salt al-Basri. Al-Mizzi said: Ali bin Zayd narrated from him, and he did not mention anyone else, whereas his son Khalid bin Abi al-Salt has also narrated from him, as mentioned in al-Tabarani's work, and that is this hadith. The rest of the narrators of this report have been declared trustworthy.
