Musannaf Ibn Abi Shaybah 2973 — Those who permitted squatting (iqa)

Al-A'mash says: I saw Atiyyah sitting between the two prostrations on the buttocks with the shins pressed against the thighs. I asked him about it, and he said: I saw Sayyiduna Abdullah bin al-Zubayr, Sayyiduna Ibn Umar and Sayyiduna Ibn Abbas (may Allah be pleased with them), and they would sit between the two prostrations on the buttocks with the shins pressed against the thighs.
