It was narrated from Abu Sa’eed that the Messenger of Allah ﷺ said:
“The two who are entrusted with the Trumpet have two horns in their hands, waiting until they will be commanded (to blow them).”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبَّادُ بْنُ الْعَوَّامِ، عَنْ حَجَّاجٍ، عَنْ عَطِيَّةَ، عَنْ أَبِي سَعِيدٍ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " إِنَّ صَاحِبَىِ الصُّورِ بِأَيْدِيهِمَا - أَوْ فِي أَيْدِيهِمَا - قَرْنَانِ يُلاَحِظَانِ النَّظَرَ مَتَى يُؤْمَرَانِ " .
