RIGHTEOUSNESS IS A TRAVELER'S BEST PROVISION
On beginning a journey, the Prophet Muhammad SAWS would say: "O Allah, we ask of Thee, in this journey of ours, righteousness and piety, and to (be able to) perform such deeds that are pleasing to You."
Fiqh-us-Sunnah, Volume 2, Number 119B
A man once approached the Prophet and said: "I am intending to go out on a journey, please (offer a prayer for me)." The Prophet replied: "May Allah grant you the provision of righteousness. . .And may He make it easy for you to do virtuous deeds, wherever you may be."
Al-Tirmidhi, Hadith 235
The Prophet also said: "Be in this world as if you are a stranger or a traveler."
Sahih Al-Bukhari, Volume 8, Hadith 425
