We were with the Prophet ﷺ at al-Batha while he was in a red tent, and a few people were with him. Bilal came and gave the call to prayer, and I kept following his mouth as it turned this way and that.
أخبرنا عبد الرحمن بن محمد بن سلام قال حدثنا إسحق الأزرق قال حدثنا سفيان عن عون بن أبي جحيفة
كنا مع النبي ﷺ بالبطحاء وهو في قبة حمراء وعنده أناس يسير فجاءه بلال فأذن فجعل يتبع فاه هاهنا وهاهنا
