Lady Aisha (may Allah be pleased with her) narrates: I heard the Prophet Muhammad (peace and blessings be upon him) say: "The Imam is a guarantor, and the Mu'adhdhin is trustworthy. May Allah guide the Imams and forgive the Mu'adhdhins." (Imam Ibn Hibban, may Allah have mercy on him, says:) This narration was heard by Abu Salih Saman from Lady Aisha (may Allah be pleased with her) as we have mentioned, and he also heard this narration from Abu Hurairah (may Allah be pleased with him) as a Marfu' (attributed to the Prophet) hadith. So, once he narrated it from Lady Aisha (may Allah be pleased with her), and once from Abu Hurairah (may Allah be pleased with him), and once he narrated it as a Mawquf (stopped at the companion) narration. He did not narrate it as a Marfu' hadith. And when A'mash heard this narration from Abu Salih from Abu Hurairah (may Allah be pleased with him) as a Mawquf narration, and he heard this narration from Abu Salih from his father from Abu Hurairah (may Allah be pleased with him) as a Marfu' hadith, then the person who inserted A'mash between Suhail and his father became confused, because A'mash heard this narration from Suhail. It is not that Suhail heard this narration from A'mash.
