What is the ruling on performing Witr in travel?
Chapter on the Times When Prayer is Prohibited
Al-Mughni
Book of Prayer
Primary text
If Witr is performed in travel after the initial obligatory prayers, two rak'ahs should precede the single Witr rak'ah. A separation of time between the preceding two rak'ahs and the Witr rak'ah is permissible, but it is preferable for them to be consecutive or closely connected.
