From Khawlah bint Al Hakim As-Sulamiyyah, that the Messenger of Allah (ﷺ) said: “Whoever stops at a stopping place and then says: ‘I seek refuge in Allah’s Perfect Words from the evil of what He has created, (A`ūdhu bi-kalimātillāhit-tāmmāti min sharri mā khalaq)’ nothing shall harm him until he departs from that stopping place of his.”
Jami` at-Tirmidhi Book 48, Hadith 68
← Previous Hadith When a matter would worry the Prophet (ﷺ), he would raise his head up toward the sky and say: “Glory is to Allah, the Magnificent (Subḥān Allāhil-`Aẓīm).” And when he would strive in supplication; he would say: “O the Living, O Sustainer (Yā Ḥayyu yā Qayyūm).”

Jami` at-Tirmidhi Book 48, Hadith 67 Next Hadith → “When the Prophet (ﷺ) would travel, and he would mount his riding camel, he would gesture with his finger” – and Shu`bah stretched out his finger – “and say: ‘O Allah You are the companion on the journey, and the caretaker for the family, O Allah, accompany us with Your protection, and return us in security, O Allah, I seek refuge in You from the difficulties of the journey, and from returning in great sadness (Allāhumma antaṣ-ṣāḥibu fis safari wal-khalīfatu fil-ahli, Allāhumma aṣḥabnā bi nuṣḥika waqlibnā bi-dhimmah, Allāhummazwi lanal-arḍa wa hawwin `alainas-safar, Allāhumma innī a’ūdhu bika min wa`thā’is-safari wa ka’ābatil-munqalab).’”
