I heard the Messenger of Allah ﷺ saying The Mu'adhdhins will have the longest necks on the Day of Resurrection.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ الْمُؤَذِّنُونَ أَطْوَلُ النَّاسِ أَعْنَاقًا يَوْمَ الْقِيَامَةِ وَحَدَّثَنِيهِ إِسْحَاقُ بْنُ مَنْصُورٍ أَخْبَرَنَا أَبُو عَامِرٍ حَدَّثَنَا سُفْيَانُ عَنْ طَلْحَةَ بْنِ يَحْيَى عَنْ عِيسَى بْنِ طَلْحَةَ قَالَ سَمِعْتُ مُعَاوِيَةَ يَقُولُ قَالَ رَسُولُ اللَّهِ ﷺ بِمِثْلِهِ  

When Satan hears the call to prayer, he runs away to a distance like that of Rauha. Sulaimin said: I asked him about Rauha. He replied: It is at a distance of thirty-six miles from Medina.  

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ إِنَّ الشَّيْطَانَ إِذَا سَمِعَ النِّدَاءَ بِالصَّلاَةِ ذَهَبَ حَتَّى يَكُونَ مَكَانَ الرَّوْحَاءِ قَالَ سُلَيْمَانُ فَسَأَلْتُهُ عَنِ الرَّوْحَاءِ فَقَالَ هِيَ مِنَ الْمَدِينَةِ سِتَّةٌ وَثَلاَثُونَ مِيلاً  

Abu Mu'awiya narrated it on the authority of A'mash with the same chain of transmitters.  

عَنِ الأَعْمَشِ بِهَذَا الإِسْنَادِ  

When Satan hears the call to prayer, he turns back and breaks the wind so as not to hear the call being made, but when the call is finished he turns round and distracts (the minds of those who pray), and when he hears the Iqama, he again runs away so as not to hear its voice and when it subsides, he comes back and distracts (the minds of those who stand for prayer).  

عَنِ النَّبِيِّ ﷺ قَالَ إِنَّ الشَّيْطَانَ إِذَا سَمِعَ النِّدَاءَ بِالصَّلاَةِ أَحَالَ لَهُ ضُرَاطٌ حَتَّى لاَ يَسْمَعَ صَوْتَهُ فَإِذَا سَكَتَ رَجَعَ فَوَسْوَسَ فَإِذَا سَمِعَ الإِقَامَةَ ذَهَبَ حَتَّى لاَ يَسْمَعَ صَوْتَهُ فَإِذَا سَكَتَ رَجَعَ فَوَسْوَسَ  

The Messenger of Allah ﷺ said: When the Mu'adhdhin calls to prayer, Satan runs back vehemently.  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا أَذَّنَ الْمُؤَذِّنُ أَدْبَرَ الشَّيْطَانُ وَلَهُ حُصَاصٌ  

The person with me looked towards the enclosure, but saw nothing. I made a mention of that to my father. He said: If I knew that you would meet such a situation I would have never sent you (there), but (bear in wind) whenever you hear such a call (from the evil spirits) pronounce the Adhan. for I have heard Abu Huraira say that the Messenger of Allah (may peace be upbn him) said: Whenever Adhan is proclaimed, Satan runs back vehemently.  

وَمَعِي غُلاَمٌ لَنَا أَوْ صَاحِبٌ لَنَا فَنَادَاهُ مُنَادٍ مِنْ حَائِطٍ بِاسْمِهِ قَالَ وَأَشْرَفَ الَّذِي مَعِي عَلَى الْحَائِطِ فَلَمْ يَرَ شَيْئًا فَذَكَرْتُ ذَلِكَ لأَبِي فَقَالَ لَوْ شَعَرْتُ أَنَّكَ تَلْقَى هَذَا لَمْ أُرْسِلْكَ وَلَكِنْ إِذَا سَمِعْتَ صَوْتًا فَنَادِ بِالصَّلاَةِ فَإِنِّي سَمِعْتُ أَبَا هُرَيْرَةَ يُحَدِّثُ عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ قَالَ إِنَّ الشَّيْطَانَ إِذَا نُودِيَ بِالصَّلاَةِ وَلَّى وَلَهُ حُصَاصٌ  

The Apostle ﷺ said When the call to prayer is made, Satan runs back and breaks wind so as not to hear the call being made, and when the call is finished. he turns round. When Iqama is proclaimed he turns his back, and when it is finished he turns round to distract a man, saying: Re- member such and such; remember such and such, referring to something the man did not have in his mind, with the result that he does not know how much he has prayed.  

أَنَّ النَّبِيَّ ﷺ قَالَ إِذَا نُودِيَ لِلصَّلاَةِ أَدْبَرَ الشَّيْطَانُ لَهُ ضُرَاطٌ حَتَّى لاَ يَسْمَعَ التَّأْذِينَ فَإِذَا قُضِيَ التَّأْذِينُ أَقْبَلَ حَتَّى إِذَا ثُوِّبَ بِالصَّلاَةِ أَدْبَرَ حَتَّى إِذَا قُضِيَ التَّثْوِيبُ أَقْبَلَ حَتَّى يَخْطِرَ بَيْنَ الْمَرْءِ وَنَفْسِهِ يَقُولُ لَهُ اذْكُرْ كَذَا وَاذْكُرْ كَذَا لِمَا لَمْ يَكُنْ يَذْكُرُ مِنْ قَبْلُ حَتَّى يَظَلَّ الرَّجُلُ مَا يَدْرِي كَمْ صَلَّى  

" He (the man saying the prayer) does not know how much he has prayed.  

عَنِ النَّبِيِّ ﷺ بِمِثْلِهِ غَيْرَ أَنَّهُ قَالَ حَتَّى يَظَلَّ الرَّجُلُ إِنْ يَدْرِي كَيْفَ صَلَّى
