Ayesha reported,

When the Messenger of Allah ﷺ raised his head from bowing, he would not prostrate until he had stood up straight. When he raised his head from prostration, he would not prostrate again until he had sat up straight. He would spread out his left leg and sit on it.

Ibn Majah 893

عن عائشة قالت

كان رسول الله ﷺ إذا رفع رأسه من الركوع لم يسجد حتى يستوي قائما وإذا سجد فرفع رأسه لم يسجد حتى يستوي جالسا وكان يفترش رجله اليسرى
