Narrated to us ʿUbaydullāh ibn Muʿādh: narrated to us my father: narrated to us Shuʿbah, from Sawādah, who said: I heard Samurah ibn Jundub — may Allah be pleased with him — while he was delivering a sermon, narrating from the Prophet ﷺ that he said: "Do not let Bilāl's call (to prayer) deceive you, nor this whiteness [of the horizon], until the dawn becomes apparent" — or he said — "until the dawn breaks."
