Abu Juhaifah narrated: "I saw Bilal calling the Adhan, and turning, and his (face) was following here and there, and his (index) fingers were in his ears, and Allah's Messenger (ﷺ) was in a small red tent" - "I think," he (one of the narrators) said, "it was made from a hide" - so Bilal went out in front of him with an Anazah which he planted (in the ground) at Batha. Allah's Messenger (ﷺ) prayed facing it, and a dog and a donkey passed in front of him; he was wearing a red Hullah, and it is as if I am now looking at the radiance of his shins." Sufyan said: "We think that it was a Hibrah."
