الأذان والإقامة
‘Ali (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "The Muezzin is responsible for the Adhān, and the leader of the congregation is responsible for the Iqāmah."
عن علي -رضي الله عنه- مرفوعاً: «المؤذن أملك بالأذان، والإمام أملك بالإقامة».
شرح الحديث :
The noble Hadīth explains that the Muezzin is more entitled to determine the time of calling the Adhān, and that the Imām is more entitled to determine the time of calling the Iqāmah.
