Does the tremor resulting from obsessive-compulsive disorder (waswas) and stress during prayer invalidate it, and is it considered excessive movement that invalidates prayer?

We advise you to strive in repelling the whispers (waswas) and turning away from them, and to consult trustworthy doctors and the counseling section on our website. Trembling and shivering do not affect the validity of the prayer and are not among the movements that invalidate it, so do not pay attention to them.
