Keutamaan muadzin: mengeraskan suara ketika adzan, kesaksian makhluk terhadap suara muadzin pada hari kiamat
Imam Bukhari : 574حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ قَالَ أَخْبَرَنَا مَالِكٌ عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَبْدِ اللَّهِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ أَبِي صَعْصَعَةَ الْأَنْصَارِيِّ ثُمَّ الْمَازِنِيِّ عَنْ أَبِيهِ أَنَّهُ أَخْبَرَهُ أَنَّ أَبَا سَعِيدٍ الْخُدْرِيَّ قَالَ لَهُإِنِّي أَرَاكَ تُحِبُّ الْغَنَمَ وَالْبَادِيَةَ فَإِذَا كُنْتَ فِي غَنَمِكَ أَوْ بَادِيَتِكَ فَأَذَّنْتَ بِالصَّلَاةِ فَارْفَعْ صَوْتَكَ بِالنِّدَاءِ فَإِنَّهُ لَا يَسْمَعُ مَدَى صَوْتِ الْمُؤَذِّنِ جِنٌّ وَلَا إِنْسٌ وَلَا شَيْءٌ إِلَّا شَهِدَ لَهُ يَوْمَ الْقِيَامَةِ قَالَ أَبُو سَعِيدٍ سَمِعْتُهُ مِنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ
Narrated to us 'Abdullah bin Yusuf, he Sa'd informed us Malik from Abdurrahman bin Abdullah bin 'Abdurrahman bin Abu Sha'sha'ah Al Anshari Al Mazini from his father, that he informed him that Abu Sa'id Al Khudri Sa'dto him, 'I see you love sheep and the desert. When you are with your sheep or in your desert and call the prayer, raise your voice with the call, for nothing hears the voice of the mu'adhdhin, whether jinn, human, or anything else, except it will testify for him on the Day of Resurrection.' Abu Sa'id Sa'd 'I heard it from the Messenger of Allah, peace be upon him.'
