When the Messenger of Allah [SAW] traveled, he would say: "Allahumma inni a'udhu bika min wa'tha'is-safari, wa kabatil-munqalabi, wal-hawri ba'dal-kawri, wa da'watil-mazlumi, wa su'il-munzari fil-ahli wal-mali wal-walad (O Allah, I seek refuge with You from the hardships of travel and the sorrows of return, from loss after plenty, from the supplication of the one who has been wronged, and seeing some calamity befall my family or wealth or child.)"
أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ إِذَا سَافَرَ قَالَ اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ وَعْثَاءِ السَّفَرِ وَكَآبَةِ الْمُنْقَلَبِ وَالْحَوْرِ بَعْدَ الْكَوْرِ وَدَعْوَةِ الْمَظْلُومِ وَسُوءِ الْمَنْظَرِ فِي الأَهْلِ وَالْمَالِ وَالْوَلَدِ
