"I heard the Messenger of Allah ﷺ 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.'" (Using translation from Nasāʾī 678)   

قَالَ رَسُولُ اللهِ ﷺ إِذَا سَمِعْتُمُ الْمُؤَذِّنَ يُؤَذِّنُ فَقُولُوا كَمَا يَقُولُ وَصَلُّوا عَلَيَّ فَإِنَّهُ لَيْسَ أَحَدٌ يُصَلِّي عَلَيَّ صَلَاةً إِلَّا ﷺ عَشْرًا وَسَلُوا اللهَ لِيَ الْوَسِيلَةَ فَإِنَّ الْوَسِيلَةَ مَنْزِلَةٌ فِي الْجَنَّةِ لَا يَنْبَغِي أَنْ تَكُونَ إِلَّا لِعَبْدٍ مِنْ عِبَادِ اللهِ وَأَرْجُو أَنْ أَكُونَهُ وَمَنْ سَأَلَهَا لِي حَلَّتْ لَهُ شَفَاعَتِي يَوْمَ الْقِيَامَةِ  

[Machine] The Prophet ﷺ said, "When you hear the caller to prayer, and then the reciter tells us about Saeed ibn Abi Ayoub, and Abu Abdullah Al-Hafiz narrated to us, and Abu Abdullah Muhammad ibn Ya'qub narrated to us, and Muhammad ibn Ismail narrated to us, and Muhammad ibn Salama Al-Muradi narrated to us, and Abdullah ibn Wahb narrated from Haywah and Saeed ibn Abi Ayoub, and others narrated from Ka'b ibn 'Alqamah, he mentioned it with its isnad (chain of narrators), and its meaning. And he said, 'And I hope that I am the one (referred to in the narration), so whoever asks for my intercession, it will be granted to him.'"  

سَمِعَ النَّبِيَّ ﷺ يَقُولُ إِذَا سَمِعْتُمُ الْمُؤَذِّنَ ثُمَّ حَدَّثَنَا الْمُقْرِئُ نَحْوَ حَدِيثِهِ عَنْ سَعِيدِ بْنِ أَبِي أَيُّوبَ 1932 وَأَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ ثنا أَبُو عَبْدِ اللهِ مُحَمَّدُ بْنُ يَعْقُوبَ ثنا مُحَمَّدُ بْنُ إِسْمَاعِيلَ أنا مُحَمَّدُ بْنُ سَلَمَةَ الْمُرَادِيُّ ثنا عَبْدُ اللهِ بْنُ وَهْبٍ عَنْ حَيْوَةَ وَسَعِيدِ بْنِ أَبِي أَيُّوبَ وَغَيْرِهِمَا عَنْ كَعْبِ بْنِ عَلْقَمَةَ فَذَكَرَهُ بِإِسْنَادِهِ وَمَعْنَاهُ وَقَالَ وَأَرْجُو أَنْ أَكُونَ أَنَا هُوَ فَمَنْ سَأَلَ لِيَ الْوَسِيلَةَ حَلَّتْ لَهُ شَفَاعَتِي  

"The Messenger of Allah ﷺ 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." (Using translation from Nasāʾī 680)   

قَالَ رَسُولُ اللهِ ﷺ مَنْ قَالَ حِينَ يَسْمَعُ النِّدَاءُ اللهُمَّ إِنِّي أَسْأَلُكَ بِحَقِّ هَذِهِ الدَّعْوَةِ التَّامَّةِ وَالصَّلَاةِ الْقَائِمَةِ آتِ مُحَمَّدًا الْوَسِيلَةَ وَالْفَضِيلَةَ وَابْعَثْهُ الْمَقَامَ الْمَحْمُودَ الَّذِي وَعَدْتَهُ إِنَّكَ لَا تُخْلِفُ الْمِيعَادَ حَلَّتْ لَهُ شَفَاعَتِي  

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. (Using translation from Abū Dāʾūd 525)   

عَنْ رَسُولِ اللهِ ﷺ قَالَ مَنْ قَالَ حِينَ يَسْمَعُ الْمُؤَذِّنَ وَأَنَا أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللهُ وَحْدَهُ لَا شَرِيكَ لَهُ وَأَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ رَضِيتُ بِاللهِ رِبًّا وَبِمُحَمَّدٍ رَسُولًا وَبِالْإِسْلَامِ دِينًا غُفِرَ لَهُ  

[Machine] "The Messenger of Allah (Peace be upon him) taught me to say at the time of Maghrib Adhan: 'O Allah, this is the coming of Your night and the departure of Your day, and the voices of Your callers. So forgive me in my book.' And Ghayruhu narrated from Al-Qasim ibn Ma'n, who narrated from Al-Mas'udi and Abdulrahman ibn Ishaq, who narrated from Abu Kathir and he added: 'And the presence of your prayer.'"  

عَلَّمَنِي رَسُولُ اللهِ ﷺ أَنْ أَقُولَ عِنْدَ أَذَانِ الْمَغْرِبِ اللهُمَّ هَذَا إِقْبَالُ لَيْلِكَ وَإِدْبَارُ نَهَارِكَ وَأَصْوَاتُ دُعَاتِكَ فَاغْفِرْ لِي كَذَا فِي كِتَابِي وَقَالَ غَيْرُهُ عَنِ الْقَاسِمِ بْنِ مَعْنٍ قَالَ ثنا الْمَسْعُودِيُّ وَرَوَاهُ عَبْدُ الرَّحْمَنِ بْنُ إِسْحَاقَ عَنْ أَبِي كَثِيرٍ وَزَادَ فِيهِ وَحُضُورُ صَلَاتِكَ
