Musannaf Ibn Abi Shaybah 2817 — How a woman sits in prayer

Ibn Jurayj said: I said to Ata: Should a woman sit in the tashahhud on her left side? He said: Yes. I said: Is that preferable to you than the right side? He said: Yes; she should keep her body drawn together while sitting as much as she can. I said: If a woman sits in the tashahhud as a man sits, or brings her left foot out from under her buttocks, what is the ruling? He said: Once she has drawn her body together, it does her no harm whichever way she sits.
