Musannaf Ibn Abi Shaybah 4123 — Those who deemed prayer at midday

Al-Aswad said: Alqamah and I came upon a written scroll, and we took it to Sayyiduna Abdullah (may Allah be pleased with him) and sat at his door. When the sun had passed its zenith, or was about to, he got up and sent his slave-girl, saying: "See who is at the door." She went back and told him: "Alqamah and al-Aswad." He said: "Permit them to come in to me." We went in and he said: "It seems you have been sitting at the door for a long time." We said: "Yes." He said: "Then why did you not ask permission to come in?" We said: "We thought you might be asleep." He said: "Do not think this of me! This is the hour whose prayer we used to liken to the tahajjud prayer."
