Q 6: Is Salah offered by a person who places his hand by his sides valid? Is it permissible to follow these people or whoever places their hands on their chest? May a person who places their hands by their sides be declared a disbeliever? Is it better to place hands on the chest or to place them by the sides after rising from Ruku` (bowing)? What did the Prophet (peace be upon him) used to do?
