When you hear the call (to prayer), repeat what the Mu'adhdhin pronounces.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا سَمِعْتُمُ النِّدَاءَ فَقُولُوا مِثْلَ مَا يَقُولُ الْمُؤَذِّنُ  

When you hear the Mu'adhdhin, repeat what he says, then invoke a blessing on me, for everyone who invokes a blessing on me will receive ten blessings from Allah; then beg from Allah al-Wasila for me, which is a rank in Paradise fitting for only one of Allah's servants, and I hope that I may be that one. If anyone who asks that I be given the Wasila, he will be assured of my intercession.  

أَنَّهُ سَمِعَ النَّبِيَّ ﷺ يَقُولُ إِذَا سَمِعْتُمُ الْمُؤَذِّنَ فَقُولُوا مِثْلَ مَا يَقُولُ ثُمَّ صَلُّوا عَلَىَّ فَإِنَّهُ مَنْ صَلَّى عَلَىَّ صَلاَةً صَلَّى اللَّهُ عَلَيْهِ بِهَا عَشْرًا ثُمَّ سَلُوا اللَّهَ لِيَ الْوَسِيلَةَ فَإِنَّهَا مَنْزِلَةٌ فِي الْجَنَّةِ لاَ تَنْبَغِي إِلاَّ لِعَبْدٍ مِنْ عِبَادِ اللَّهِ وَأَرْجُو أَنْ أَكُونَ أَنَا هُوَ فَمَنْ سَأَلَ لِيَ الْوَسِيلَةَ حَلَّتْ لَهُ الشَّفَاعَةُ  

The Messenger of Allah ﷺ said: When the Mu'adhdhin says: Allah is the Greatest, Allah is the Greatest, and one of you should make this response: Allah is the Greatest, Allah is the Greatest; (and when the Mu'adhdhin) says: I testify that there is no god but Allah, one should respond: I testify that there is no god but Allah, and when he says: I testify that Muhammad is the Messenger of Allah, one should make a response: I testify that Muhammad is Messenger of Allah. When he (the Mu'adhdhin) says: Come to prayer, one should make a response: There is no might and no power except with Allah. When he (the Mu'adhdhin) says: Come to salvation, one should respond: There is no might and no power except with Allah, and when he (the Mu'adhdhin) says: Allah is the Greatest, Allah is the Greatest, then make a response: Allah is the Greatest, Allah is the Greatest. When he (the Mu'adhdhin) says: There is no god but Allah, and he who makes a re- sponse from the heart: There is no god but Allah, he will enter Paradise.  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا قَالَ الْمُؤَذِّنُ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ فَقَالَ أَحَدُكُمُ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ ثُمَّ قَالَ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ قَالَ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ ثُمَّ قَالَ أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ قَالَ أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ ثُمَّ قَالَ حَىَّ عَلَى الصَّلاَةِ قَالَ لاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ ثُمَّ قَالَ حَىَّ عَلَى الْفَلاَحِ قَالَ لاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ ثُمَّ قَالَ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ قَالَ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ ثُمَّ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ مِنْ قَلْبِهِ دَخَلَ الْجَنَّةَ  

The Messenger of Allah ﷺ said: If anyone says on hearing the Mu'adhdhin: I testify that there is no god but Allah alone. Who has no partner, and that Muhammad is His servant and His Messenger, (and that) I am satisfied with Allah as my Lord, with Muhammad as Messenger. and with Islam as din (code of life), his sins would be forgiven. In the narration transmitted by Ibn Rumh the words are:" He who said on hearing the Mu'adhdhin and verity I testify." ' Qutaiba has not mentioned his words:" And I."  

عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ قَالَ مَنْ قَالَ حِينَ يَسْمَعُ الْمُؤَذِّنَ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ وَأَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ رَضِيتُ بِاللَّهِ رَبًّا وَبِمُحَمَّدٍ رَسُولاً وَبِالإِسْلاَمِ دِينًا غُفِرَ لَهُ ذَنْبُهُ قَالَ ابْنُ رُمْحٍ فِي رِوَايَتِهِ مَنْ قَالَ حِينَ يَسْمَعُ الْمُؤَذِّنَ وَأَنَا أَشْهَدُ وَلَمْ يَذْكُرْ قُتَيْبَةُ قَوْلَهُ وَأَنَا
