Abdul Aziz bin Rafee’ says that I saw Hazrat Abu Mahzoorah come, while a man had already given the adhan, he (Abu Mahzoorah) gave the adhan and said the iqamah.

A narrator reports that Hazrat Ibn Umm Maktum would call the adhan and Hazrat Bilal would say the iqamah, and sometimes Hazrat Bilal would call the adhan and Hazrat Ibn Umm Maktum would say the iqamah.

Hasan says that there is no harm if one person gives the adhan and another person says the iqamah.

It is narrated from Hazrat Zuhri that the Messenger of Allah, peace and blessings be upon him, said: The one who has given the adhan should also say the iqamah.

Hazrat Ziyad bin Harith Sudai narrates that I was with the Holy Prophet (peace and blessings be upon him) on a journey. I gave the call to prayer (adhan). When Hazrat Bilal intended to say the iqamah, the Holy Prophet (peace and blessings be upon him) said, "The brother from Suda' has given the adhan; the one who gives the adhan should also say the iqamah." Thus, I then said the iqamah.
