It is narrated from Sayyiduna Sa’ib bin Yazid that during the blessed era of the Prophet ( صلی اللہ علیہ وسلم ), there was only one muezzin appointed, who would give the adhan after the Prophet ( صلی اللہ علیہ وسلم ) sat on the pulpit, and after descending from the pulpit, he would also say the iqamah. This continued during the time of Sayyiduna Abu Bakr as-Siddiq and Sayyiduna Umar as well.
