Obligatory, Necessary, or Strongly Recommended

The Hanafi school regards witr as wajib, necessary, a binding duty just short of the obligation of the five daily prayers, such that deliberately omitting it is a serious fault and a missed witr must be made up. The other Sunni schools classify it as a confirmed sunnah, strongly recommended but not binding in the same degree. The practical effect is that a Hanafi worshipper treats witr with much the same seriousness as an obligatory prayer, while a Shafii or Maliki worshipper values it highly but not identically.

Witr often includes a supplication of humility and dependence recited in the final standing, and the practice of raising the hands for it. In Ramadan the witr is commonly prayed in congregation as the seal of the tarawih. In Twelver Shia practice a single-rak'ah witr concludes the night prayer with its own recommended supplications.

The prayer's odd-numbered structure is itself textually grounded: a hadith has the Prophet declare that God is witr, one, and loves what is odd-numbered, tying the prayer's very shape to a name and attribute of God. Schools further differ over the placement of the qunut supplication recited within it, the Hanafi school reciting it before bowing in every witr prayer year-round, while other schools generally reserve a comparable supplication to particular occasions or place it after rising from bowing, a difference in detail that nonetheless reflects genuinely separate lines of transmitted practice rather than mere local custom.
