The travel supplication
Matches the Arabic text of Sahih Muslim 1342
اللَّهُ أَكْبَرُ، اللَّهُ أَكْبَرُ، اللَّهُ أَكْبَرُ، سُبْحَانَ الَّذِي سَخَّرَ لَنَا هَذَا وَمَا كُنَّا لَهُ مُقْرِنِينَ، وَإِنَّا إِلَى رَبِّنَا لَمُنْقَلِبُونَ، اللَّهُمَّ إِنَّا نَسْأَلُكَ فِي سَفَرِنَا هَذَا الْبِرَّ وَالتَّقْوَى، وَمِنَ الْعَمَلِ مَا تَرْضَى، اللَّهُمَّ هَوِّنْ عَلَيْنَا سَفَرَنَا هَذَا وَاطْوِ عَنَّا بُعْدَهُ، اللَّهُمَّ أَنْتَ الصَّاحِبُ فِي السَّفَرِ، وَالْخَلِيفَةُ فِي الْأَهْلِ، اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ وَعْثَاءِ السَّفَرِ، وَكَآبَةِ الْمَنْظَرِ، وَسُوءِ الْمُنْقَلَبِ فِي الْمَالِ وَالْأَهْلِ
Allah is the Greatest (three times). Glory be to the One who has subjected this to us, though we could not have done it ourselves; and to our Lord we shall return. O Allah, we ask You on this journey for righteousness and piety, and deeds that please You. O Allah, make this journey easy for us and shorten its distance. O Allah, You are the Companion on the journey and the Guardian of the family. O Allah, I seek refuge in You from the hardships of travel, distressing sights, and an ill return in wealth and family.
The words "Glory be to the One… we shall return" are from Surah al-Zukhruf (43:13-14).
