It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "The imam is responsible (for the prayer) and the muezzin is entrusted (with the correct time of the call to prayer). «اَرْشَدَاللهُ الأ ئِمّةَ ، وَغَفَرَلِلْمَؤَذِّنِيْنَ» O Allah, grant guidance and righteousness to the imams and forgiveness to the muezzins." This is the narration of Ashajj. Imam Abu Bakr (may Allah have mercy on him) says that this narration has been reported by Ibn Numayr from A‘mash, and he has corrupted this narration.
