حَدَّثَنَا أَيُّوبُ بْنُ مُحَمَّدٍ الْهَاشِمِيُّ، حَدَّثَنَا عَبْدُ الْوَاحِدِ بْنُ زِيَادٍ، عَنْ حَجَّاجِ بْنِ أَرْطَاةَ، عَنْ عَوْنِ بْنِ أَبِي جُحَيْفَةَ، عَنْ أَبِيهِ، قَالَ أَتَيْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ بِالأَبْطَحِ وَهُوَ فِي قُبَّةٍ حَمْرَاءَ فَخَرَجَ بِلاَلٌ فَأَذَّنَ فَاسْتَدَارَ فِي أَذَانِهِ وَجَعَلَ إِصْبَعَيْهِ فِي أُذُنَيْهِ ‏.‏

It was narrated from 'Awn bin Abu Juhaifah that his father said: "I came to the Messenger of Allah in Abtah, when he was in a red tent. Bilal came out and gave the call to prayer, turning around and putting his fingers in his ears." Translation Not Available
