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.

Narrated Ziyad ibn al-Harith as-Suda'i: 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.

Narrated AbuHurayrah: The Prophet (ﷺ) said: The mu'adhdhin will receive forgiveness to the extent to which his voice reaches, and every moist and dry place will testify on his behalf; and he who attends (the congregation of) prayer will have twenty-five prayers recorded for him and will have expiation for sins committed between every two times of prayer.

Abu Hurairah reported the Messenger of Allah (ﷺ) as saying: when the call to prayer is made; the devil turns his back and breaks wind so as not to hear the call being made; but when the call is finished, he turns round. When the second call to prayer (iqamah) is made, he turns his back, and when the second call is finished, he turns round and suggest notions in the mind of the man (at prayer) to distract his attention, saying: remember such and such, referring to something the man did not have n mind, with the result that he does not know how much he has prayed.

This tradition has also been transmitted through a different chain of narrators by Abu Hurairah who reported it in a similar manner from the Messenger of Allah (ﷺ).

Narrated A woman from Banu an-Najjar: Urwah ibn az-Zubayr reported on the authority of a woman from Banu an-Najjar. She said: My house was the loftiest of all the houses around the mosque (of the Prophet (ﷺ) at Medina). Bilal used to make a call to the morning prayer from it. He would come there before the break of dawn and wait for it. When he saw it, he would yawn and say: O Allah, I praise you and seek Your assistance for the Quraysh so that they might establish Thine religion. He then would make the call to prayer. She (the narrator) said: By Allah, I do not know whether he ever left saying these words on any night.

Abu Juhaifah reported: I came to the prophet (ﷺ) at Mecca; he was sitting in a tent made of leather. Then Bilal came out and called to prayer. I looked at his mouth following him this side and that side (i.e., right and left). Later at his Messenger of Allah (ﷺ) came out clad in a red suit, i.e, wearing the sheets of the Yemen, of the Qatri design. The version narrated by Musa has the word; “I saw Bilal going towards al-Abtah”. He then made a call to prayer. When he reached the words “ come to prayer, come to salvation”. He turned his neck right and left, respectively; he did not turn himself (with his whole body). He then entered (his house) and came out with a lancet. The narrator then reported the rest of the tradition.

Abu Sa’id al-Khudri reported the Messenger of Allah (May peace be upon him) as saying : When you hear the Adhan, you should repeat the same words as the mu’adhdhin pronounces.

‘Abd Allah b. ‘Amr b. al-As reported the Messenger of Allah (May peace be upon him) as saying: when you hear the mu'adhdhin repeat what he says, invoke a blessing on me, for everyone who invoke one blessing on me will receive ten blessings from Allah. Then ask Allah to give me the wasilah, which is a rank in paradise fitting for only one of Allah’s servants, and I hope that I may be the one. If anyone asks Allah that I be given the wasilah, he will be assured of my intercession.

Narrated Abdullah ibn Amr ibn al-'As: A man said: Messenger of Allah, the mu'adhdhins excel us. The Messenger of Allah (ﷺ) said: Say (the same words) as they say, and when you come to the end, make a petition and that will be granted to you.

Sa’d b. Abi Waqqas reported the Messenger of Allah (May peace be upon him) as saying : If anyone says when he hears the MU’ADHDHIN : “And I testify that there is no god but Allah alone who has no partner and that Muhammad is His servant and Apostle: I am satisfied with Allah as lord, with Muhammad as apostle and with Islam as religion”, he will be forgiven.

‘A’ishah said that when the Messenger of Allah (ﷺ) heard the MU’ADHDHIN uttering the testimony, he would say: “And I too, and I too”.

‘Umar b. al-khattab reported the Messenger of Allah (May peace be upon him) as saying; When the MU’ADHDHIN says: “Allah is most great, Allah is most great”, and one of you says in response: “Allah is most great”, Allah is most great; then says: “ I testify tht there is no god but Allah”, and he says in response: “I testify that there is no god but Allah”, then say:” I testify that Muhammad is the Messenger of Allah”, and he makes the response: “ I testify that Muhammad is the Messenger of Allah”, then says: “Come to prayer”, and he makes the response: “There is no might and no power except in Allah”: then says: “ Allah is most great, Allah is most great”, and he makes the response: “Allah is most great”, then says: “There is no god but Allah”, if he says this from his heart, he enter Paradise.

Narrated AbuUmamah, or one of the Companion of the Prophet: Bilal began the Iqamah, and when he said: "The time for prayer has come," the Prophet (ﷺ) said: "May Allah establish it and cause it to continue."

Jabir b. ‘Abd Allah reported the Messenger of Allah (ﷺ) as saying: if anyone says when he hears the call to prayer : “O Allah, Lord of this perfect call and of the prayer which is established for all time, grant Muhammad the wasilah and excellency, and raise him up in a praiseworthy position which Thou hast promised, he will be assured of my intercession.

Narrated Umm Salamah, Ummul Mu'minin: The Messenger of Allah (ﷺ) taught me to say when the adhan for the sunset prayer was called; "O Allah, this is the time when Thy night comes on, Thy day retires, and the voices of Thy summoners are heard, so forgive me."

Narrated Abdullah ibn Umar: Bilal made a call to prayer before the break of dawn; the Prophet (ﷺ), therefore, commanded him to return and make a call: Lo! the servant of Allah (i.e. I) had slept (hence this mistake). The version of Musa has the addition: He returned and made a call: Lo! the servant of Allah had slept. Abu Dawud said: This tradition has been narrated by al-Darawardi from 'Ubaid Allah on the authority of Ibn 'Umar saying: There was a mu'adhdhin of 'Umar, named Mas'ud. He then narrated the rest of the tradition. This version is more correct than that one.

Nafi' reported : A mu'adhdhin of ‘Umar, named Masruh, called the Adhan for the morning prayer before the break of dawn; ‘Umar commanded him (to repeat). The narrator reported the tradition in a similar way. Abu Dawud said: This tradition has been transmitted by al-Darawardi from ‘Ubaid Allah on the authority of Ibn ‘Umar, saying: there was a mu'adhdhin of ‘Umar, named Mas’ud. He then narrated the rest of the tradition. This version is more correct than one.

Narrated Bilal: The Messenger of Allah (ﷺ) said to Bilal: Do not call adhan until the dawn appears clearly to you in this way, stretching his hand in latitude. Abu Dawud said: Shaddad did not see Bilal.
