Musnad Abu Ya'la al-Mawsili 112:15

Abu Kurayb narrated to us, al-Muharibi narrated to us, from ‘Amr ibn Musawir al-‘Ijli, from al-Hasan, from Anas, who said: The Messenger of Allah (may Allah bless him and grant him peace) never intended a journey at all, except that he would say when he rose from his sitting: "O Allah, by You I have spread forth, and toward You I have directed myself, and by You I have held fast. O Allah, You are my trust and You are my hope. O Allah, suffice me against what concerns me and what does not concern me, and that which You know better than I do. And provide me with piety, and forgive me my sin, and direct me toward goodness wherever I turn." He said: Then he would go out.
