Sunan an-Nasa'i, Book 7, Hadith 651 (In-Book) ⓘ

'Abdur-Rahman bin 'Abdullah bin 'Abdur-Rahman bin Abi Sa'sa'ah Al-Ansari Al-Mazini narrated that his father told him that Abu Sa'eed Al-Khudri said to him: "I see that you love sheep and the desert. When you are with your sheep or in the desert and you call the Adhan for prayer, then raise your voice, for no human, Jinn or anything else hears the voice of the Mu'adhdhin as far as it reaches, but it will bear witness for him on the Day of Resurrection." Abu Sa'eed said: "I heard it from the Messenger of Allah."

أَخْبَرَنَا مُحَمَّدُ بْنُ سَلَمَةَ، قَالَ أَنْبَأَنَا ابْنُ الْقَاسِمِ، عَنْ مَالِكٍ، قَالَ قَالَ حَدَّثَنِي عَبْدُ الرَّحْمَنِ بْنُ عَبْدِ اللَّهِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ أَبِي صَعْصَعَةَ الأَنْصَارِيُّ الْمَازِنِيُّ، عَنْ أَبِيهِ، أَنَّهُ أَخْبَرَهُ أَنَّ أَبَا سَعِيدٍ الْخُدْرِيَّ قَالَ لَهُ إِنِّي أَرَاكَ تُحِبُّ الْغَنَمَ وَالْبَادِيَةَ فَإِذَا كُنْتَ فِي غَنَمِكَ أَوْ بَادِيَتِكَ فَأَذَّنْتَ بِالصَّلاَةِ فَارْفَعْ صَوْتَكَ فَإِنَّهُ لاَ يَسْمَعُ مَدَى صَوْتِ الْمُؤَذِّنِ جِنٌّ وَلاَ إِنْسٌ وَلاَ شَىْءٌ إِلاَّ شَهِدَ لَهُ يَوْمَ الْقِيَامَةِ ‏.‏ قَالَ أَبُو سَعِيدٍ سَمِعْتُهُ مِنْ رَسُولِ اللَّهِ صلى الله عليه وسلم ‏.‏
