The Ruling on the Regular Voluntary Prayers and the Late-Night Prayer While Traveling

The Shaykh:
The best practice is to shorten the prayer. The voluntary prayers that are not performed while traveling are the regular voluntary prayers (rawatib) associated with the obligatory prayers. These are not performed, neither before nor after, except for the regular voluntary prayer of Fajr. The regular voluntary prayer of Fajr is not left off, whether one is resident or traveling. As for the regular voluntary prayers associated with Zuhr, the regular voluntary prayers associated with Maghrib, and the regular voluntary prayers associated with Isha, these are not performed by one who shortens the prayer. The one who shortens the prayer does not perform the regular voluntary prayer before or after it. As for the late-night prayer (tahajjud) and the Witr prayer, it is not befitting to leave them off. A person performs the late-night prayer if he is staying in a place, either as a voluntary prayer or as a regular practice, just as you have heard. He performs the late-night prayer on his mount. The late-night prayer is not left off.
