Sunan Ibn Majah, Chapter: The Chapters on Supplication

"The Messenger of Allah (saw) used to say" - and (one of the narrators) Abdur-Rahim said: "he used to seek refuge" - "when he traveled: 'Allahumma inni a'udhu bika min wa'tha'is-safar, wa ka'abatil-munqalab, wal-hawri ba'dal-kawr, wa da'watil-mazlum, wa su'il-manzari fil-ahli wal-mal (O Allah, I seek refuge with You from the hardships of travel and the sorrows of return, from decrease after increase, from the prayer of the one who has been wronged, and seeing some calamity befall my family or wealth).'" (One of the narrators) Abu Muawiyah added: "And when he returned he said likewise."
