It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "The imam is a guarantor and the muezzin is entrusted. May Allah Almighty guide the imams and forgive the muezzins."
(b) Imam Ahmad (may Allah have mercy on him) said: Suhayl did not hear this hadith from his father; rather, he heard it from al-A'mash.
