Musannaf Ibn Abi Shayba 21:490

Hushaym narrated to us, from Mughirah, from Ibrahim, who said: They used to say during travel: "O Allah, a reaching that reaches the best of Your forgiveness from You, and a pleasure; and in Your hand is all good, indeed You are over all things competent. O Allah, You are the companion in travel and the successor over the family. O Allah, fold the earth for us and make the travel easy for us. O Allah, we seek refuge in You from the hardship of travel, the gloominess of the return, and an evil sight in the family and wealth."
