"When the Messenger of Allah [SAW] traveled and rode his mount, he gestured with his finger - and Shu'bah (one of the narrators) stretched out his finger - and said: 'Allahumma, antas-sahibu fis-safari wal-khalifatu fil-ahli wal-mal. Allahumma, inni a'udhu bika min wa'tha'is-safari, wa kabatil-munqalabi (O Allah, You are our help when we are traveling and the One Who takes care of our families and wealth (in our absence). O Allah, I seek refuge in You from the hardships of travel and the sorrows of return.)'" (Using translation from Nasāʾī 5501)  

كَانَ رَسُولُ اللهِ ﷺ إِذَا سَافَرَ فَرَكِبَ رَاحِلَتَهُ قَالَ بِإِصْبَعِهِ وَمَدَّ شُعْبَةُ بِأُصْبُعِهِ قَالَ «اللهُمَّ أَنْتَ الصَّاحِبُ فِي السَّفَرِ وَالْخَلِيفَةُ فِي الْأَهْلِ اللهُمَّ ازْوِ لَنَا الْأَرْضَ وَهَوِّنْ عَلَيْنَا السَّفَرَ اللهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ وَعْثَاءِ السَّفَرِ وَكَآبَةِ الْمُنْقَلَبِ»
