Qiyam means standing and Qiyam Al-Layl means standing at night. In the Islamic terminology, both words refer to the voluntary night prayer, whose time extends from after Isha prayer until dawn. Other common names for Qiyam Al-Layl are Salat-ul-Layl (the night prayer), Tahajjud (from hajada, meaning remained one who awake at night), and Taraweeh (resting). A widespread misconception is that Tahajjud is a different night prayer than Qiyam or Taraweeh. It is important to clarify this misunderstanding and to make clear that the voluntary night prayer is known by different names.
