Riyad as-Salihin Hadith 983

Whenever the Messenger of Allah (ﷺ) set out on a journey, he would say by nightfall: "Ya ardu, Rabbi wa Rabbuk-illahu, a'udhu billahi min sharriki wa sharri ma fiki, wa sharri ma khuliqa fiki, wa sharri ma yadibbu 'alaiki; a'udhu billahi min sharri asadin wa aswadin, wa minal-hayyati wal-'aqrabi, wa min sakinil-baladi, wa min walidin wa ma walad [O land, my Rubb and your Rubb is Allah, I seek refuge in Him from your evils, the evils of what you contain, the evils of what has been created in you, and the evils of what walks upon you. I seek refuge in Allah from lions, black serpents, scorpions and from the inhabitants of the place, and from the parent (i.e., Satan) and his offspring who inhabit a settlement (i.e., helpers from amongst the devils)]." [Abu Dawud].
