Malik related to me that he heard that when the Messenger of
Allah, may Allah bless him and grant him peace, set foot in the
stirrup intending to travel, he would say, "In the name of Allah. O
Allah! You are my companion in the journey and the Khalifa of my
family. O Allah! Spread out the earth for us and make the journey easy
for us. O Allah! I seek refuge with You from the hardship of the
journey and from returning to sorrow and a distressing sight regarding
property and family."
Muwatta Malik Book 54, Hadith 34
