Adding or Omittintg to the Acts of Prayer Intentionally
Issue No.1115- If a person intentionally adds something to the obligatory acts of prayer, or omits from them, the prayer becomes void. However, if he adds or omits a foundational element, his prayer is void even though it may be due to not knowing the issue. Nevertheless, adding or omitting a non-foundational element does not harm the prayer provided that he has not come short in learning the issue (i.e. he was able to learn the issue yet he failed to do so).
