What is the ruling on performing prayer while standing if one can achieve standing through support?

Primary text

Standing in prayer is obligatory if one is capable of standing by leaning on a stick, resting against a wall, or leaning on one's side. This obligation is established because the individual is capable of standing without incurring harm, which necessitates standing just as if one could stand without any external support. The ruling is based on the principle that capability without harm mandates performance.
