Namaz Missed Due To Traveling
You could’ve perfomed tayammum and prayed while travelling. And if not possible, you had the option to combine Zuhr and Asar ( at Zuhr time or at Asar time considering your ease ) and combine Maghrib and Isha ( at Maghrib time or at Isha time considering your ease ). And if due to some reason, you were unable to do any of them becasue of circumstances, then whever you get time to offer salah, you should offer immediately, it will not be considered Qaza Namaz. Currently, you can compensate for your missed salah. Please see : Discussion 40073 Discussion 35095
