"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 شُعْبَةً بِإِصْبَعِهِ قَالَ «اللهُمَّ أَنْتَ الصَّاحِبُ فِي السَّفَرِ وَالْخَلِيفَةُ فِي الْأَهْلِ اللهُمَّ أَعُوذُ بِكَ مِنْ وَعْثَاءِ السَّفَرِ وَكَآبَةِ الْمُنْقَلَبِ»
