TIRMIDHI 3445:
from Mūsá —
a man said: “O Messenger of Allah ﷺ, I intend to travel, so advise me.” He said, “Hold fast to the Taqwa of Allah, and (say the) Takbir upon every elevated place.” So when the man turned away he said: “O Allah make near for him the distance, and ease for him the journey (Allāhummaṭwi lahul-arḍa wa hawwin ʿalaihis-safar).”

عن موسى —
يَا رَسُولَ اللَّهِ إِنِّي أُرِيدُ أَنْ أُسَافِرَ فَأَوْصِنِي قَالَ عَلَيْكَ بِتَقْوَى اللَّهِ وَالتَّكْبِيرِ عَلَى كُلِّ شَرَفٍ فَلَمَّا أَنْ وَلَّى الرَّجُلُ قَالَ اللَّهُمَّ اطْوِ لَهُ الأَرْضَ وَهَوِّنْ عَلَيْهِ السَّفَرَ قَالَ هَذَا حَدِيثٌ حَسَنٌ
