Narrated Abdullah ibn Zayd: The Prophet ﷺ intended to do many things for calling (the people) to prayer, but he did not do any of them. Then Abdullah ibn Zayd was taught in a dream how to pronounce the call to prayer. He came to the Prophet ﷺ and informed him. He said: Teach it to Bilal. He then taught him, and Bilal made a call to prayer. Abdullah said: I saw it in a dream and I wished to pronounce it, but he (the Prophet) said: You should pronounce iqamah.

This tradition has also been transmitted through a different chain of narrators by Abdullah bin Zaid. He said: My grandfather pronounced the Iqamah.

Narrated Ziyad ibn al-Harith as-Sudai: When the adhan for the dawn prayer was initially introduced, the Prophet ﷺ commanded me to call the adhan and I did so. Then I began to ask: Should I utter iqamah, Messenger of Allah? But he began to look at the direction of the east, (waiting) for the break of dawn, and said: No. When the dawn broke, he came down and performed ablution and he then turned to me. In the meantime his Companions joined him. Then Bilal wanted to utter the iqamah, but the Prophet ﷺ said to him: The man of Suda' has called the adhan, and he who calls the adhan utters the iqamah.
