He went to the airport to travel and shortened the prayer, but the trip did not take place. Does he have to repeat it?

Question : Now, if the plane did not land and the trip did not happen that day, does he have to repeat the prayer he shortened?

Answer : No, because he performed it in accordance with the command of Allah and in conformity with His Shari'ah, so it is accepted. This is based on the saying of the Prophet (peace and blessings be upon him) The implication of this is that whoever performs an act in accordance with the command of Allah and His Messenger, it is accepted.
