The ruling on movement during prayer and whether it affects it

Question:
May Allah reward you. From the questions of the questioner from Syria, she says: In the month of Ramadan, Honorable Shaykh, we broadcast the tarawih prayer and we see some of the people moving a lot during the prayer. What is the guidance for them? And does movement affect the validity of the prayer?

Answer:
Movement without need, which is a form of heedlessness and frivolity, affects the prayer; for what is required in prayer is khushu' (humility), which is stillness and tranquility. Allah the Exalted said: Therefore, the absence of movement indicates the absence of khushu', whereas stillness indicates khushu' in the presence of Allah (Glorified and Exalted is He). It is obligatory to refrain from movement unless it is for a need, in which case it is permissible to the extent of the need.
