Hilal bin Yasaf states that he heard Sayyiduna Mu'awiyah (may Allah be pleased with him) narrating this hadith: he heard the Prophet (peace and blessings be upon him) say: "Whoever hears the mu'adhdhin and says words like those the mu'adhdhin says will receive a reward like that of the mu'adhdhin."
Imam al-Tabarani recorded this narration in al-Mu'jam al-Kabir as a narration of Isma'il bin Ayyash from the people of the Hijaz, and in respect of those people he is da'if (weak).
