Hadith 157

Narrated Abu Hurairah (RA): Allah's Messenger (ﷺ) said: "The Mu'adhdhin has more right to [determine the time to] announce the Adhan and the Imam has more right to [determine when to] pronounce the Iqamah." [Reported by Ibn 'Adi who graded it Da'if (weak)]. al-Baihaqi has reported a similar narration from the saying of 'Ali (RA).
