Allah is the Greatest, Allah is the Greatest; I testify that there is no god but Allah, I testify that there is no god but Allah; I testify that Muhammad Is the Messenger of Allah, I testify that Muhammad is the Messenger of Allah, and it should be again repeated: I testify that there is no god but Allah, I testify that there is no god but Allah; I testify that Muhammad Is the Messenger of Allah, I testify that Muhammad is the Messenger of Allah. Come to the prayer (twice). Come to success (twice). Ishaq added: Allah is the Greatest, Allah is the Greatest; there Is no god but Allah.
“I came to the Prophet (S.A.W) with a cousin of mine” – on an another occasion he said: “with a companion of mine” – “and he said: ‘When the two of you travel, call the Adhan and the Iqamah, and let the older of you lead the prayer.'”
“We came to the Messenger of Allah (S.A.W) and we were young men close in age. He let us stay with him for twenty days. The Messenger of Allah (S.A.W) was merciful and compassionate, and he thought that we were missing our families; he asked us about those whom we had left behind of our families, so we told him, and he said: ‘Go back to your families, stay with them and teach them. Tell them when the time for prayer comes; let one of you call the Adhan and let the oldest of you lead the prayer.'”
“Abu Qilabah said to me (Ayyub): He (‘Amr) is still alive, do you want to meet him?” I met him and asked him, and he said: “When Makkah was conquered, all the people hastened to announce their Islam. My father went to announce the Islam of the poeple of our village, and when he came back we went to see him and he said: ‘By Allah, I have indeed come to you from the Messenger of Allah (S.A.W)’. He said: ‘Pray such and such a prayer at such and such a time, pray such and such a prayer at such and such a time. When the time for prayer comes let one of you call the Adhan and let the one who knows the most Qur’an lead the prayer.'”
“Bilal calls the Adhan during the night, so eat and drink until you hear Ibn Umm Maktoom calling the Adhan.”
“Al-Aswad bin Yazid narrated to me from Abu Mahdhurah that the final words of the Adhan are: ‘La ilaha illahha (there is none worthy of worship except Allah).'”
“We were with him (Ibn ‘Umar) in Jam’ (Muzdalifah), and he called the Adhan, then the Iqamah, then he led us in praying Maghrib. Then he said: ‘The prayer,’ and he led us in praying ‘Isha’, two Rak’ahs. I said: ‘What is this prayer?’ He said: ‘This is how I prayed with the Messenger of Allah (S.A.W) in this place.'”
Allah’s Messenger sat with him and taught him the Adhan word for word. Ibrahim said, “It is the same as our Adhan.” Bishr said: “So I said to him, ‘Repeat it to me.’ So he described the Adhan with At-Tarjl’.”
the Prophet taught him the Adhan with nineteen phrases, and the Iqamah with seventeen phrases.
