Qīyām Is a Foundational Element
Issue No.879- Qīyām means to stand straight, and in two places of the prayer it is obligatory and considered to be a foundational element (rukn): one while uttering takbīrat-ul-iḥrām, and the other before the rukū‘ which is called the qīyām connected to rukū‘. However, standing while reciting sūrah al-fātiḥa and the other sūrah, and also standing after rukū‘ is obligatory, but not as a foundational element.
