[Machine] I am Abu Sa'id and he was in his room, so he said to me, "O my son, when you call the Adhan, raise your voice, for I heard the Messenger of Allah ﷺ saying: 'Nothing hears it, whether it be jinn, man, stone, or anything else, except that it bears witness for him.'" And he also said to me once, "O my son, when you are in the open fields, raise your voice with the Adhan, for I heard the Messenger of Allah ﷺ saying: 'No jinn, man, stone, or anything else hears it except that it bears witness for him.'"  

لِي أَبُو سَعِيدٍ وَكَانَ فِي حِجْرِهِ فَقَالَ لِي يَا بُنَيَّ إِذَا أَذَّنْتَ فَارْفَعْ صَوْتَكَ بِالْأَذَانِ فَإِنِّي سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ لَيْسَ شَيْءٌ يَسْمَعُهُ إِلَّا شَهِدَ لَهُ جِنٌّ وَلَا إِنْسٌ وَلَا حَجَرٌ وقَالَ مَرَّةً يَا بُنَيَّ إِذَا كُنْتَ فِي الْبَرَارِيِّ فَارْفَعْ صَوْتَكَ بِالْأَذَانِ فَإِنِّي سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ لَا يَسْمَعُهُ جِنٌّ وَلَا إِنْسٌ وَلَا حَجَرٌ وَلَا شَيْءٌ يَسْمَعُهُ إِلَّا شَهِدَ لَهُ
