Traveler's dua

سُبْحَانَ الَّذِي سَخَّرَ لَنَا هَذَا وَمَا كُنَّا لَهُ مُقْرِنِينَ وَإِنَّا إِلَى رَبِّنَا لَمُنْقَلِبُونَ

Subhanal-lathee sakhkhara lana hatha wa ma kunna lahu muqrineen, wa inna ila Rabbina lamunqaliboon

Glory to Him who has subjected this to us, and we could never have it by our own efforts. And to our Lord we shall surely return.

Reference: Surah Az-Zukhruf 43:13-14
