Musannaf Ibn Abi Shaybah 2496 — A woman opening the prayer: how high

Ibn Jurayj said: I asked Ata: "When saying the opening takbir in prayer, should a woman gesture with her hands like a man?" He said: "She should not gesture like a man; rather, she should keep her hands very low and drawn close to herself." Ata also said: "A woman has a posture that is not that of men, and if she leaves it, there is no harm."
