Question:
May Allah reward you. The honorable scholar says: You mentioned that the rawatib (regular voluntary prayers) are not performed while traveling, except for the Fajr rawatib. The question is: Is the Witr also left off while traveling? And are the other recommended prayers, such as the Duha prayer and others, left off?
