‘Abdullāh ibn Sarjis (may Allah be pleased with him) reported: When the Messenger of Allah (may Allah's peace and blessings be upon him) traveled, he would seek refuge [in Allah] from the hardships of the journey, from having a change of heart, adverse conditions replacing good ones, the prayer of an oppressed person, and from seeing a misfortune occurring to his family and wealth.
