The دعاء for travel anxiety is: 'Allahumma inna naj'aluka fi nuhurihim wa na'udhu bika min shururihim' — O Allah, we place You before them (as a shield) and we seek refuge in You from their evil. هذا الدعاء seeks Allah's protection from all sources of fear and anxiety encountered during travel.
اللَّهُمَّ إِنَّا نَجْعَلُكَ فِي نُحُورِهِمْ وَنَعُوذُ بِكَ مِنْ شُرُورِهِمْ
Allahumma inna naj'aluka fi nuhurihim wa na'udhu bika min shururihim.
Meaning: O Allah, we place You before them (as a shield against them) and we seek refuge in You from their evil.
Source: Sunan Abu Dawud #1537هذا الدعاء places Allah as a barrier and shield between the supplicant and any source of danger or fear. النبي (صلى الله عليه وسلم) would recite it whenever he apprehended danger from any group or situation. It is a powerful الدعاء for الحجاج who may feel anxious about the journey, crowded conditions, or unfamiliar environments.
اللَّهُمَّ إِنَّا نَجْعَلُكَ فِي نُحُورِهِمْ وَنَعُوذُ بِكَ مِنْ شُرُورِهِمْ
When the Prophet (peace be upon him) feared a people, he would say: 'Allahumma inna naj'aluka fi nuhurihim wa na'udhu bika min shururihim.'
