اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ سُبْحَانَ الَّذِي سَخَّرَ لَنَا هَذَا وَمَا كُنَّا لَهُ مُقْرِنِينَ وَإِنَّا إِلَى رَبِّنَا لَمُنقَلِبُونَ
Allahu Akbar, Allahu Akbar, Allahu Akbar. Subhanal-ladhi sakhkhara lana hadha wa ma kunna lahu muqrinin, wa inna ila Rabbina lamunqalibun
Allah is the Greatest (3x). Glory to the One who has subjected this for us, and we could not have done it ourselves. And indeed, to our Lord we will return.
The full travel sequence: three takbirs followed by the Quranic verse. The Prophet ﷺ would also add: "We ask You in this journey for righteousness, piety, and deeds that please You." He would say "Allahu Akbar" when ascending high ground and "SubhanAllah" when descending into valleys — a geographic rhythm of dhikr that turns the landscape into a prayer rug.
