It is narrated from Hazrat Abu Hurairah (may Allah be pleased with him) that whenever the Holy Prophet (peace and blessings be upon him) set out on a journey, he would recite this supplication: O Allah, I seek refuge in You from the hardships of travel, from distress upon return, and from witnessing any evil in my family and wealth. O Allah, You are my companion in travel and my successor among my family. O Allah, fold the earth for us and make the journey easy for us.
