It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with him) that in the time of the Messenger of Allah (peace and blessings be upon him), the words of the adhan were said twice each, and in the iqamah, once each; however, in the iqamah, the mu’adhdhin would say“Qad qamatis salah, qad qamatis salah”(twice). And whenever we heard the iqamah, we would perform ablution and come out for prayer. Imam Shu’bah says: This is all that I remember.

Sayyiduna Anas bin Malik (may Allah be pleased with him) says: Sayyiduna Bilal (may Allah be pleased with him) was commanded to say the words of the adhan twice each, and to say the words of the iqamah once each.

(Second chain) Sayyiduna Anas (may Allah be pleased with him) said: Sayyiduna Bilal (may Allah be pleased with him) was commanded to say two phrases for the adhan and one phrase for the iqamah, except for the words "Qad qamatis salah."

Sayyiduna Abu Juhaifah (may Allah be pleased with him) says: I saw Sayyiduna Bilal (may Allah be pleased with him) giving the adhan, that he would turn (while saying "Hayya 'ala-s-Salah" and "Hayya 'ala-l-Falah") and I was watching his mouth turning this way and that. In another narration, it is further stated: that he was turning to the right and left and had both his fingers in his ears.

Ibn Abi Mahzura, narrating from his father or grandfather, says: The Messenger of Allah, peace and blessings be upon him, specified the call to prayer (adhan) for us and our freed slaves, providing water to the pilgrims for Banu Hashim, and carrying the Black Stone for Banu Abd al-Dar.

Sayyiduna Uthman bin Abi al-As (may Allah be pleased with him) says: I said, "O Messenger of Allah! Make me the imam of my people." The Prophet (peace and blessings be upon him) said: (Alright), you are their imam. Take care of the weakest among them and appoint such a muezzin who does not take wages for his call to prayer.

The freed slave of the Messenger of Allah, Sayyiduna Abu Rafi’ (may Allah be pleased with him) says: Whenever the Messenger of Allah (peace and blessings be upon him and his family) heard the mu’adhdhin (caller to prayer), he would repeat what he said. When the mu’adhdhin reached“Hayya ‘ala-s-Salah, Hayya ‘ala-l-Falah,”the Messenger of Allah (peace and blessings be upon him and his family) would say:“La hawla wa la quwwata illa billah.”

It is narrated from Sayyiduna Abdullah bin Rabee’ah Salmi (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) was on a journey. He (peace and blessings be upon him) heard a mu’adhdhin saying:“Ashhadu an la ilaha illallah,”so he (peace and blessings be upon him) also said:“Ashhadu an la ilaha illallah.”Then when the mu’adhdhin said:“Ashhadu anna Muhammadan Rasulullah,”he (peace and blessings be upon him) said:“Ashhadu anni Muhammadan Rasulullah.”Then the Noble Prophet (peace and blessings be upon him) said:“You will find him to be a shepherd of goats or someone who has gone far from his family.”Abdullah bin Rabee’ah says: When the Prophet (peace and blessings be upon him) descended into a valley, he passed by a (dead) kid of a goat that had been thrown away. The Prophet (peace and blessings be upon him) said:“Do you consider this insignificant in the eyes of its owners? (That is why they threw it away.) Surely, this world is even more insignificant in the sight of Allah than this kid is to its owners.”

It is narrated from Sayyidah Aisha Siddiqa (may Allah be pleased with her) that when the Messenger of Allah (peace and blessings be upon him) used to hear the caller to prayer (mu'adhdhin), he would say: "I bear witness that there is no god but Allah, and I bear witness that Muhammad is the Messenger of Allah."

It is narrated from Sayyida Umm Habibah (may Allah be pleased with her) that whenever the Noble Prophet (peace and blessings be upon him) heard the muezzin giving the call to prayer, he would repeat whatever the muezzin said until he became silent.
