Musannaf Ibn Abi Shaybah 7330 — The imam praying sitting

Abdullah bin Hubayrah said: Sayyiduna Usayd bin Hudayr (may Allah be pleased with him) used to lead his people, Banu Abd al-Ashhal, in prayer. He once fell ill, and when he came out to them after his illness, the people said to him: "Step forward and lead the prayer." He said: "I do not have the strength to lead the prayer." The people said: "As long as you are among us, no one other than you will lead us in prayer." Sayyiduna Usayd said to them: "Then all of you sit down," and he led them in prayer sitting.
