Stopping a Blind Person from Passing

Q: Salaah-65: A blind man passed in front as I got up from Ruku. Will the salaah be affected if I used my hand to stop him?

Answer: Stopping the blind man in the above case will not constitute Amal Katheer, so the salaah need not be repeated. And Allaah knows best what is most correct.
