The Supplication of Al-Qunut
Question:
What is the ruling on reciting the supplication of Al-Qunut in the Witr prayer during the nights of Ramadhan? Is it permissible to leave it off?
Answer:
Al-Qunut is a sunnah ( i.e., supererogatory act) in the Witr prayer. If a person leaves it off sometimes there is no harm in that.
