In Ruku‘ position she should place her hands above her knees on her thighs so as not to bend down very much to lift up her rear end. When sitting she should sit on her posteriors unlike a man. When bowing down for prostration she should first bring down her knees before her hands, then place herself on the ground. When sitting she should keep her thighs together and raise her knees from the ground.

When moving to stand up a woman should rise upward without allowing her rear end to be seen being lifted up first.” صحيح - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (15/157))
