Sayyiduna Abu Juhayfah (may Allah be pleased with him) said: I saw Sayyiduna Bilal (may Allah be pleased with him) giving the call to prayer, and he would turn his mouth this way and that way. And Sufyan (while narrating it) turned his face to the right and to the left.
Yahya said: Sufyan said that Hajjaj used to narrate it from Awn saying that he mentioned "and he turned around during his adhan" as well; but when we met Awn ourselves, he did not mention "turning around" in it.
