Keutamaan muadzin: mengeraskan suara ketika adzan, kesaksian makhluk terhadap suara muadzin pada hari kiamat
Imam Ahmad : 10607حَدَّثَنَا سُفْيَانُ حَدَّثَنِي ابْنُ أَبِي صَعْصَعَةَ عَبْدُ اللَّهِ بْنُ عَبْدِ الرَّحْمَنِ عَنْ أَبِيهِ قَالَ قَالَ لِي أَبُو سَعِيدٍ وَكَانَ فِي حُجْرَةٍ فَقَالَ لِي يَا بُنَيَّ إِذَا أَذَّنْتَ فَارْفَعْ صَوْتَكَ بِالْأَذَانِ فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ لَيْسَ شَيْءٌ يَسْمَعُهُ إِلَّا شَهِدَ لَهُ جِنٌّ وَلَا إِنْسٌ وَلَا حَجَرٌ و قَالَ مَرَّةً يَا بُنَيَّ إِذَا كُنْتَ فِي الْبَرَارِيِّ فَارْفَعْ صَوْتَكَ بِالْأَذَانِ فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ لَا يَسْمَعُهُ جِنٌّ وَلَا إِنْسٌ وَلَا حَجَرٌ وَلَا شَيْءٌ يَسْمَعُهُ إِلَّا شَهِدَ لَهُ قَالَ أَبِي وَسُفْيَانُ مُخْطِئٌ فِي اسْمِهِ وَالصَّوَابُ عَبْدُ الرَّحْمَنِ بْنُ عَبْدِ اللَّهِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ أَبِي صَعْصَعَةَ
Narrated to us [Sufyan] said: has narrated to me [Ibn Abu Sha'sha'ah Abdullah bin Abdurrahman] from [his father], he said: [Abu Sa'id] said to me while he was in the room, he said: "O my son, when you call to prayer then raise your voice, indeed I heard The Messenger of Allah peace and blessings be upon him say: "No one hears it, be it a jinn, a human or a stone unless it will testify to it." Occasionally he said: "O my son, if you are in the desert then raise your voice when calling to prayer, because I heard The Messenger of Allah peace and blessings be upon him say: "Neither the jinn can hear it, man, stone or whatever unless he will testify for it." My father said: and Sufyan was wrong in pronouncing his name, the correct one was Abdurrahman bin Abdullah bin Abdurrahman bin Abu Sha'sha'ah.
