Musannaf Ibn Abi Shayba 28:1098

Hushaym narrated to us, from Mughirah, from Ibrahim, who said: They used to say during travel: "O Allah, [grant us] a provision that reaches the best of forgiveness from You, and contentment. In Your hand is all good; indeed, You are over everything 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 hardships of travel, the gloominess of the return, and a bad sight regarding family and wealth."
