Supplication; A prayer to God alone. Duʿā is used to thank Allah or to request something from Him. It is regarded by Muslims as an act of worship and is a means of seeking closeness to God. 

A personal duʿā can be performed at any time and there are no set phrases nor language in which it must be performed in. 

Duʿā also refers to written supplications, often passed down from the Maʿṣūmin (infallibles), which has a set text and may be recited individually or as a group activity. Some examples include Duʿā Kumayl, normally recited on Thursday evenings; Duʿā al-Nudbah, commonly read on Friday mornings, or Duʿā al-Arafah recited on the 9th of Dhu’l Hijjah.
