Sayyiduna Anas (may Allah be pleased with him) narrates: The Messenger of Allah ordered Sayyiduna Bilal (may Allah be pleased with him) to say the words of the adhan in even numbers and the words of the iqamah in odd numbers.

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: In the blessed era of the Prophet (peace and blessings be upon him), the adhan consisted of two, two phrases, and the iqamah consisted of one phrase, however, «قد قامت الصلوۃ» was said twice. (Imam Ibn Hibban, may Allah have mercy on him, says:) The narrator named Abu Ja’far was the imam of the Ansar’s mosque in Kufa; his name is Muhammad bin Muslim bin Mihran bin Muthanna, while the narrator named Abu Muthanna’s name is Muslim bin Muthanna.

Sayyiduna Anas (may Allah be pleased with him) narrates: The people searched for something through which they could inform others, and that thing would be a specific sign for prayer. Sayyiduna Bilal (may Allah be pleased with him) was commanded to say the words of the adhan in even numbers and the words of the iqamah in odd numbers.

Sayyiduna Abdullah bin Zaid (may Allah be pleased with him) narrates: When the Prophet Muhammad (peace and blessings be upon him) was commanded regarding the bell, that it should be rung so that people may gather for prayer, then at night while I was asleep, a person came to me who was wearing two green sheets. In his hand was a bell which he was holding. I said: O servant of Allah! Will you sell this bell? He asked: What will you do with it? I replied: I will call people to prayer with it. He asked: Shall I not guide you to something better than this? I replied: Yes. He said: When you intend to announce, then say: «اللهُ أَكْبَرُ» , «اللَّهُ أَكْبَرُ» , «اللَّهُ أَكْبَرُ» , «اللَّهُ أَكْبَرُ» , «أَشْهَدُ أَن لَّا إِلَهَ إِلَّا اللَّهُ» , «أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ» , «أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ» , «أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللهِ» , «حَيَّ عَلَى الصَّلَاةِ» , «حَيَّ عَلَى الصَّلَاةِ» , «حَيَّ عَلَى الْفَلَاحِ» , «حَيَّ عَلَى الْفَلَاحِ» «اللَّهُ أَكْبَرُ» , «اللَّهُ أَكْبَرُ» , «لَا إِلَهَ إِلَّا اللَّهُ» Then he moved back a little and said: When you are about to establish the prayer (i.e., say the Iqamah), then say: «اللَّهُ أَكْبَرُ» , «اللَّهُ أَكْبَرُ» , «أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللهُ» , «أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ» , «حَيَّ عَلَى الصَّلَاةِ» «حَيَّ عَلَى الْفَلَاحِ» , «قَدْ قَامَتِ الصَّلَاةُ» , «قَدْ قَامَتِ الصَّلَاةُ» , «اللَّهُ أَكْبَرُ» , «اللَّهُ أَكْبَرُ» , «لَا إِلَهَ إِلَّا اللَّهُ» (Sayyiduna Abdullah bin Zaid (may Allah be pleased with him) narrates:) When morning came, I went to the Prophet Muhammad (peace and blessings be upon him) and informed him about this. The Prophet (peace and blessings be upon him) said: If Allah wills, this dream will become reality. Get up and teach these words to Bilal which you have seen (in the dream), so he may call the Adhan accordingly, for his voice is louder than yours. So I stood with Sayyiduna Bilal (may Allah be pleased with him) and I kept telling him those words and he kept calling the Adhan accordingly. When Sayyiduna Umar (may Allah be pleased with him) heard his voice, he was at his house at the place called "Zawra". He came dragging his cloak and said: By the One Who sent Muhammad (peace and blessings be upon him) with the truth! I was also shown a dream like he was shown. So the Prophet (peace and blessings be upon him) said: All praise is due to Allah alone for this.

Abdullah Muhairiz narrates: He was under the guardianship of Sayyiduna Abu Mahdhurah. When he was about to go to Syria, he narrates: I said to Sayyiduna Abu Mahdhurah, "I am about to go to Syria. I will be asked about the incident of the Adhan, so please tell me about it." Sayyiduna Abu Mahdhurah told me: We were a group of people who set out and were at a place on the way to Hunayn. At that time, the Prophet Muhammad (peace be upon him) was returning from Hunayn. The Prophet (peace be upon him) encountered us on the way. The Messenger of Allah's mu'adhdhin gave the Adhan for prayer in the presence of the Prophet (peace be upon him). We heard his voice. We had moved aside from the road, so we began to repeat those words loudly in mockery. The Prophet (peace be upon him) heard this voice. He inquired: "Who among you knows the person whose voice I have heard?" The narrator says: Then we were brought and made to stand before the Prophet (peace be upon him). The Prophet (peace be upon him) asked: "Whose voice was that among you?" The narrator says: Everyone pointed towards me. The narrator says: Then the Prophet (peace be upon him) let all of them go and kept me with him. There was nothing more disliked to me than what the Messenger of Allah (peace be upon him) commanded me. He ordered me to give the Adhan. The Prophet (peace be upon him) himself taught me the words of the Adhan. He said: Say this: «اللهُ أَكْبَرُ» «اللَّهُ أَكْبَرُ» «اللَّهُ أَكْبَرُ» «اللهُ أَكْبَرُ» «أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللهُ» «أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ» «أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ» «أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ» Then he said to me: "Do tarji‘ in it and raise your voice." Then he said these words: «أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ» «أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللهُ» «اَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ» «أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ» «حَيَّ عَلَى الصَّلَاةِ» «حَيَّ عَلَى الصَّلَاةِ» «حَيَّ عَلَى الْفَلَاحِ» «حَيَّ عَلَى الْفَلَاحِ» «اللَّهُ أَكْبَرُ» «اللَّهُ أَكْبَرُ» «لَا إِلَهَ إِلَّا اللَّهُ» When he finished giving the Adhan, the Prophet (peace be upon him) called me and gave me a pouch in which there was a little silver, and he prayed: "O Allah! Bless it and bless him." The narrator says: I said, "O Messenger of Allah! Command me to give the Adhan." The Prophet (peace be upon him) said: "We command you." The narrator says: Then all the dislike I had in my heart for the Prophet (peace be upon him) turned into love. Then I went to the governor appointed by the Prophet (peace be upon him), Sayyiduna ‘Attab bin Asid, and under the command of the Prophet (peace be upon him), I began to give the Adhan in Makkah. Ibn Jurayj says: Many members of my family narrated this narration to me from Ibn Muhairiz, from Sayyiduna Abu Mahdhurah.

Sayyiduna Abu Mahdhurah (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) taught me 19 words for the Adhan and 17 words for the Iqamah. «اللهُ أَكْبَرُ» «اللَّهُ أَكْبَرُ» «اللهُ أَكْبَرُ» «اللهُ أَكْبَرُ» «أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ» «أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ» «أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ» «أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللهِ» «حَيَّ عَلَى الصَّلَاةِ» «حَيَّ عَلَى الصَّلَاةِ» «حَيَّ عَلَى الْفَلَاحِ» «حَيَّ عَلَى الْفَلَاحِ» «اللَّهُ أَكْبَرُ» «اللَّهُ أَكْبَرُ» «لَا إِلَهَ إِلَّا اللَّهُ» .“The words of the Iqamah are: «اللهُ أَكْبَرُ» «اللَّهُ أَكْبَرُ» «اللَّهُ أَكْبَرُ» «اللهُ أَكْبَرُ» «أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ» «أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ» «أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ» «أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللهِ» «حَيَّ عَلَى الصَّلَاةِ» «حَيَّ عَلَى الصَّلَاةِ» «حَيَّ عَلَى الْفَلَاحِ» «حَيَّ عَلَى الْفَلَاحِ» «قَدْ قَامَتِ الصَّلَاةُ» «قَدْ قَامَتِ الصَّلَاةُ» «اللَّهُ أَكْبَرُ» «اللَّهُ أَكْبَرُ» «لَا إِلَهَ إِلَّا الله» .”

Muhammad bin Abdul Malik narrates from his father, from his grandfather (Sayyiduna Abu Mahdhurah): I said, "O Messenger of Allah! Teach me the method of the adhan." The narrator states: The Prophet (peace and blessings of Allah be upon him) passed his hand over the front of my head and said, "Say this: «الله الكبَرُ» «اللَّهُ أَكْبَرُ» «اللَّهُ أَكْبَرُ» «اللَّهُ أَكْبَرُ» — in this, raise your voice. Then say: «أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ» «أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللهُ» «أَشْهَدُ أَنَّ مُحَمَّدًا رَسُوْلُ اللَّهِ» «أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ» — in this, lower your voice. Then, while saying the words of testimony, raise your voice: «أَشْهَدُ أن لا إله إلا اللهِ» «أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللهُ» «أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ» «مَرَّتَيْنِ وَحَيَّ عَلَى الصَّلَاةِ» «حَيَّ عَلَى الصَّلَاةِ» «حَيَّ عَلَى الْفَلَاحِ» «حَيَّ عَلَى الْفَلَاحِ» . If it is the adhan for Fajr, then say: «الصَّلَاةُ خَيْرٌ مِنَ النَّوْمِ» «الصَّلَاةُ خَيْرٌ مِنَ النَّوْمِ» «اللهُ أَكْبَرُ» «اللَّهُ أَكْبَرُ» «لَا إِلَهَ إِلَّا اللَّهُ» ."

Lady Aisha Siddiqa (may Allah be pleased with her) narrates: When the Prophet Muhammad (peace and blessings be upon him) would hear the muezzin (giving the call to prayer), he would say: I also affirm (what you are saying).

Isa bin Talha narrates: We were with Sayyiduna Muawiyah (may Allah be pleased with him). He heard the muezzin say «اللہ اکبر» «الله اکبر» , so Sayyiduna Muawiyah (may Allah be pleased with him) also said «اللہ اکبر» «اللہ اکبر» . When the muezzin said «اشهد ان لا اله الا الله» , Sayyiduna Muawiyah (may Allah be pleased with him) said: I also bear witness to this. When the muezzin said «اشهد ان محمدا رسول الله» , Sayyiduna Muawiyah (may Allah be pleased with him) said: I also bear witness to this. Then Sayyiduna Muawiyah (may Allah be pleased with him) explained: I heard the Noble Prophet (peace and blessings be upon him) responding to the adhan in this manner.

Hafs bin Asim narrates from his father, from his grandfather Sayyiduna Umar (may Allah be pleased with him) that the Prophet Muhammad (peace and blessings be upon him) said: When the muezzin says «اللہ اکبر» «اللہ اکبر» , then any one of you (i.e., the person hearing the adhan) should say «الله اكبر» «الله اکبر» ; when he says «اشهد ان لا الله الا الله» , then (the listener) should say «اشهد ان لا اله الا الله» ; then when he says «اشهد ان محمد رسول اللہ» , (the listener) should say «اشهد ان محمدا رسول الله» ; then when he says «حی علی الصلوة» , (the listener) should recite «لا حول ولا قوة الا باللہ» ; then when he says «حی علی الفلاح» , (the listener) should recite «لا حول ولا قوة الا باللہ» ; then when he says «الله اکبر» «اللہ اکبر» , (the listener) should say «اللہ اکبر» «اللہ اکبر» ; then when he says «لا الله الا اللہ» , the listener should say «لا الله الا اللہ» ; so the person who responds to the adhan in this way will enter Paradise.
