When one stops at any place during the journey to spend the night, then one should recite the following Duaa:
اَعُوذُ بِكَلِمَاتِ اللهِ التَّامَّاتِ مِن شَرِّ مَا خَلَق
I seek protection through the complete (and perfect) words of Allah Ta’ala (i.e. His mubaarak names and attributes) from the evil (harm) of His creation.
عن خولة بنت حكيم السلمية أنها سمعت رسول الله صلى الله عليه وسلم يقول إذا نزل أحدكم منزلا فليقل أعوذ بكلمات الله التامات من شر ما خلق فإنه لا يضره شيء حتى يرتحل منه (مسلم رقم 2708)
Hazrat Khaula (radhiyallahu ‘anha) reports that she heard Rasulullah (sallallahu ‘alaihi wasallam) say: “If anyone of you halts at any place during the journey, then he should recite the following duaa. Through reciting the duaa, no harm will come to him from the time he halts till the time he departs.”
اَعُوذُ بِكَلِمَاتِ اللهِ التَّامَّاتِ مِن شَرِّ مَا خَلَقَ
