Sayyiduna Ubadah bin Samit (may Allah be pleased with him) and Sayyiduna Shaddad bin Aws (may Allah be pleased with him), both of these companions narrate: "There are two types of twilight (shafaq): the red one and the white one. When the red twilight disappears, then the time for prayer begins. Similarly, there are two types of true dawn (subh sadiq): one that is vertical and one that is horizontal. When the horizontal one ends, then the time for prayer begins."

Sayyiduna Abu Hurairah (may Allah be pleased with him) said: "Shafaq refers to redness."

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: The Noble Prophet (peace and blessings be upon him) said: "By 'shafaq' is meant redness; when the shafaq disappears, the prayer becomes obligatory (i.e., its time begins)."

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: "By 'shafaq' is meant redness."
