Bilal reported,

He was calling the adhan, turning his face this way and that, with his fingers in his ears, while the Messenger of Allah ﷺ was inside a red dome-tent of his, which I think he said was made of leather. Bilal came out before him carrying the anazah, planted it in the Batha, and the Messenger of Allah ﷺ prayed facing it, while dogs and donkeys passed in front of him. He was wearing a red garment, and it is as though I am still looking at the gleam of his shins.Sufyan said, "We consider it to have been a Yemeni hibarah cloak."

Sahih

حدثنا محمود بن غيلان حدثنا عبد الرزاق أخبرنا سفيان الثوري عن عون بن أبي جحيفة عن أبيه قال

رأيت بلالا

يؤذن ويدور ويتبع فاه ها هنا وها هنا وإصبعاه في أذنيه ورسول الله ﷺ في قبة له حمراء أراه قال من أدم فخرج بلال بين يديه بالعنزة فركزها بالبطحاء فصلى إليها رسول الله ﷺ يمر بين يديه الكلب والحمار وعليه حلة حمراء كأني أنظر إلى بريق ساقيه قال سفيان نراه حبرة
