حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ قَالَ حَدَّثَنَا سُفْيَانُ عَنْ عَوْنِ بْنِ أَبِي جُحَيْفَةَ عَنْ أَبِيهِ أَنَّهُ رَأَی بِلَالًا يُؤَذِّنُ فَجَعَلْتُ أَتَتَبَّعُ فَاهُ هَهُنَا وَهَهُنَا بِالْأَذَانِ

Narrated `Aun bin Abi Juhaifa: My father said, "I saw Bilal turning his face from side to side while pronouncing the Adhan for the prayer."
