"I was with Mu'awiyah when the Mu'adhdhin called the Adhan. Muawiyah said what the Mu'adhdhin said, but when he said: 'Hayya 'alas-salah (come to prayer),' he said: 'La hawla wa la quwwata illa Billah (There is no power and no strength except with Allah);' and when he said: 'Hayya 'alal-falah (come to prosperity),' he said: 'La hawla wa la quwwata illa Billah (There is no power and no strength except with Allah).' After that he said what the Mu'adhdhin said, then he said: 'I heard the Messenger of Allah (S.A.W) saying exactly like that.'"
"I heard the Messenger of Allah (S.A.W) say: 'When you hear the Mu'adhdhin then say what he says, and do Salah upon me, for whoever does Salah upon me once, Allah will Salah upon him ten (times). Then ask Allah to grant me Al-Wasilah, which is a position in paradise which only one of the slaves of Allah will attain, and I hope that I will be the one. Whoever asks for Al-Wasilah for me, will be entitled to my intercession.'"
It was narrated from Sa'd bin Abi Waqqas that the Messenger of Allah (S.A.W) said:
"Whoever says, when he hears the Mu'adhdhin: 'Ashhadu an la ilaha illallah wahdahu la sharika lahu wa anna Muhammadan 'abduhu wa Rasuluhu, raditu Billahi Rabban, wa bil-Islami dinan was bi Muhammadin Rasula (I bear witness that there is none worthy of worship except Allah alone, with no partner or associate, and that Muhammad is the His slave and Messenger; I am content with Allah as my Lord, Islam as my religion and Muhammad as my Messenger),' his sins will be forgiven."
"The Messenger of Allah (S.A.W) said: 'Whoever says, when he hears the call to prayer: "Allahumma rabba hadhihid-da'wat it-tammah was-salat il-qaimah, ati Muahmmadan al-wasilah wal-fadilah, wab'athu maqaman mahmudan alladhi wa'adtahu (O Allah, Lord of this perfect call and the prayer to be offered, grant Muhammad the privilege (of interceding) and also the eminence, and resurrect him to the praised position that you have promised),' will be granted my intercession on the Day of Resurrection."
It was narrated that 'Abdullah bin Mughaffal said:
"The Messenger of Allah (S.A.W) said: 'Between each two Adhans [1] there is a prayer, between each two Adhans there is a prayer, between each two Adhans there is a prayer, for whoever wants to do it."
[1]Meaning, between the Adhan and Iqamah.
Chapter 39: Prayer Between The Adhan And The Iqamah - كتاب الأذان
أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا أَبُو عَامِرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ عَمْرِو بْنِ عَامِرٍ الأَنْصَارِيِّ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ كَانَ الْمُؤَذِّنُ إِذَا أَذَّنَ قَامَ نَاسٌ مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم فَيَبْتَدِرُونَ السَّوَارِيَ يُصَلُّونَ حَتَّى يَخْرُجَ النَّبِيُّ صلى الله عليه وسلم وَهُمْ كَذَلِكَ وَيُصَلُّونَ قَبْلَ الْمَغْرِبِ وَلَمْ يَكُنْ بَيْنَ الأَذَانِ وَالإِقَامَةِ شَىْءٌ .
It was narrated that Anas bin Malik said:
"When the Mu'adhdhin called the Adhan, some of the Companions of the Prophet (S.A.W) would get up and rush to the pillars (in the Masjid) and pray until the Prophet (S.A.W) came out and they were like that. They would pray before Maghrib and there was nothing between the Adhan and Iqamah."
It was narrated from Ash'ath bin Abi Ash-Sha'tha' that his father said:
"I saw Abu Hurairah, when a man passed by in the Masjid until he parted from it - after the call. Abu Hurairah said: 'This man has indeed disobeyed Abu Al-Qasim (S.A.W).'"
"Between the time when he finished 'Isha' prayer and Fajr, the Prophet (S.A.W) used to pray eleven Rak'ahs, saying the Taslim after each two Rak'ahs, then praying Witr as one Rak'ah. He would prostrate for as long as it takes one of you to recite fifty verses, then he would raise his head. When the Mu'adhdhin finished the call to Fajr prayer and he could see the dawn, he would pray two brief Rak'ahs, then he would go out with him." Some of these narrators (Ibn Abi Dhi'b, Yunus and 'Amr bin Al-Harith) added some phrases not mentioned by the others in the Hadith.
It was narrated from Makhramah bin Sulaiman that Kuraib - the freed slave of Ibn 'Abbas - told him:
"I asked Ibn 'Abbas: 'How did the Messenger of Allah (S.A.W) pray at night?' He said: 'He prayed eleven Rak'ahs including Witr, then he slept deeply until I could hear him snoring, then Bilal came to him and said: "The prayer, O Messenger of Allah!" Then he got up and prayed two brief Rak'ahs then led the people in prayer, and he did not perform Wudu'.'"
