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)].

وَعَنْ أَبِي هُرَيْرَةَ ‏- رضى الله عنه ‏- قَالَ : قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ اَلْمُؤَذِّنُ أَمْلَكُ بِالْأَذَانِ , وَالْإِمَامُ أَمْلَكُ بِالْإِقَامَةِ } رَوَاهُ اِبْنُ عَدِيٍّ وَضَعَّفَهُ .‏ [1]‏
