What is the ruling on a worshipper raising one or both of their feet during prostration?

Prostration must be performed on the seven bodily parts: the forehead and nose, the two palms, the two knees, and the tips of the two feet. It is not permissible to lift any of these parts. If someone fails to prostrate on any of these parts, their prayer is invalid, and their prostration, and consequently their prayer, is nullified.
