If the traveler prays Zhuhr and `Asr together at the time of the former then arrivers home before or after `Asr is due, his Prayer will be considered valid because traveling provides a valid excuse for the combining of prayers. The same applies to combining Maghrib and `Isha' at the time of the former.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
