The questioner : Yes, it is contrary to the prayer, as if he is not in prayer. Well, this is one opinion, but there is another opinion that if it is done in forgetfulness, the prayer is not invalidated, even if it takes the prayer out of its proper context, as long as he was in a state of forgetfulness.
