Narrated 'Abdullah bin Zaid bin Abd-Rabbihi (RA): A man appeared to me while I was asleep and told me to say, "Allahu Akbar, Allahu Akbar (Allah is the Most Great, Allah is the Most Great)" and he mentioned the Adhan with Allahu Akbar four times without Tarji', and the Iqama once except Qad qamat-is-Salah (the prayer stood ready to begin), (he repeated it twice). He ('Abdullah) said when it was morning I went to Allah's Messenger ( صلی اللہ علیہ وسلم ) and he said, "It is a true vision..." [Reported by Ahmad and Abu Dawud; at-Tirmidni and Ibn Khuzaimah graded it Sahih (authentic)] . Ahmad added to the end of the above Hadith, the story of BIlal's statement in the Fajr Adhan (morning prayer call): as-Salatu khairun minan-nawm - "Prayer is better than sleep".

Narrated Abu Mahdhura (RA): The Prophet ( صلی اللہ علیہ وسلم ) taught him the Adhan (call to prayer) and he (the narrator) mentioned the Tarji' in it. [Muslim reported it, but mentioned the phrase (Takbir) "Allah is the Most Great" at its beginning just twice. al-Khamsah reported it, but mentioned the Takbir four times.

Narrated Anas (RA): Bilal was commanded to announce the Adhan (each phrase) twice and the Iqamah (each phrase) once except "The prayer stood ready to begin" (to be pronounced twice). [Agreed upon; but Muslim did not mentioned the exception] . A narration of an-Nasa'i has: "Bilal was ordered by the Prophet ( صلی اللہ علیہ وسلم )."

Narrated Abu Juhaifa (RA): I saw Bilal calling for prayer and I would follow (looking at) his mouth (as he turned it) this (right) side and that (left) side with his fingers in his ears. [Reported by Ahmad and at-Tirmidhi who graded it Sahih (authentic)] . In a narration of Ibn Majah - 'and he put his fingers in his ears'. And also a narration of Abu Dawud - 'he turned his neck to the right and left when he reached Haiya 'alas-Salah (Come to the prayer) and did not turn his body'. And its basic meaning is in Sahihain (al-Bukhari and Muslim).

Narrated Abu Mandhura (RA): The Prophet ( صلی اللہ علیہ وسلم ) liked his voice, so he taught him the Adhan (call to prayer). [Reported by Ibn Khuzaimah] .

Narrated Jabir bin Samurah (RA): I prayed with the Prophet ( صلی اللہ علیہ وسلم ) the two 'Eids, not only once or twice, without an Adhan or an Iqamah. [Reported by Muslim] . A similar narration is in al-Bukhari and Muslim narrated by 'Abdullah bin 'Abbas (RA) and others.

Narrated Abu Qatadah (RA) in a long Hadith about their (Sahaba) sleeping late past the time of Salat (prayer): Then Bilal proclaimed the Adhan and the Prophet ( صلی اللہ علیہ وسلم ) offered the prayer (while leading the Companions) as he used to do every day. [Reported by Muslim] . Muslim also reported from Jabir (RA): The Prophet ( صلی اللہ علیہ وسلم ) came to al-Muzdalifah and offered at it both the Maghrib and 'Isha prayers with one Adhan and two Iqamah. Muslim also reported from Ibn 'Umar (RA): The Prophet ( صلی اللہ علیہ وسلم ) combined the Maghrib and 'Isha prayers with one Iqamah. Abu Dawud added the words: "for each prayer". And in another narration he reported: The Adhan was not announced for any one of them.

Narrated Ibn 'Umar and 'Aishah (RA): Allah's Messenger ( صلی اللہ علیہ وسلم ) said: "Bilal calls for prayer when it is still night, so eat and drink till Ibn Umm Maktum calls for prayer." And he (Ibn Umm Maktum) was a blind man who did not call for a prayer until he was told: "It is morning time, it is morning time." [Agreed upon] . There is an Idraj in its last part.

Narrated Ibn 'Umar (RA): Bilal called for prayer before dawn and the Prophet ( صلی اللہ علیہ وسلم ) told him to return and announce: "Lo! the slave of Allah (i.e. Bilal) had slept (hence this mistake)". [Reported by Abu Dawud, and graded as Da'if (weak)] .

Narrated Abu Sa'id al-Khudri (RA): Allah's Messenger ( صلی اللہ علیہ وسلم ) said: "When you hear the Adhan repeat what the Mu'adhdhin (the call-maker) says." [Agreed upon] . And al-Bukhari has reported similarly in a narration by Mu'awiyah (RA). And Muslim reported a narration by 'Umar (RA) regarding the virtue of repeating what the Mu'adhdhin pronounces word by word except when the Mu'adhdhin says: "Haiya 'alas-Salah, Haiya 'alal-Falah (Come to the prayer and come to the success)", one should say: "La hawla wa la quwwata illa billah [there is no might and no power except with (the help of) Allah] ."
