Can a Traveller Pray Sunnah Prayers?

All the Sunnah prayers remain for the traveller - he can worship Allah by praying them. The Duha prayer, night prayer, Witr, prayer of entering the mosque, Istikharah, and all the voluntary prayers are established for the traveller just like they are established for the resident, except for three voluntary prayers: the Sunnah of Dhuhr, the Sunnah of Maghrib and the Sunnah of Isha, because the Sunnah is that the traveller does not pray these three voluntary prayers. The remaining prayers remain legislated for the traveller just as they are legislated for the resident.
