Zuhayr ibn Harb narrated to us: Isma'il ibn 'Ulayyah narrated to us: 'Abdullah ibn Sawadah narrated to me, from his father, from Samurah ibn Jundub — may Allah be pleased with him — who said: The Messenger of Allah, peace and blessings be upon him, said: "Do not let Bilal's call to prayer deceive you, nor this whiteness — meaning the column of dawn — until it spreads out like this."
