Musannaf Ibn Abi Shaybah 2868 — Pausing and silence after the takbir

Sayyiduna Samurah bin Jundub (may Allah be pleased with him) said: The Prophet (peace and blessings be upon him) used to observe two pauses: one on beginning the prayer, and the other after finishing the recitation. Sayyiduna Imran bin Husayn (may Allah be pleased with him) found this report strange, so they asked Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) for his view by letter, and he said: Samurah speaks the truth.
