Ruling on the traveler combining the five daily prayers at the end of the day

Is it permissible for a Muslim who is traveling a long distance to combine the five daily prayers at the end of the day?
Answer: This is a great abomination that no scholar would say, combining the five daily prayers! This is a great abomination. No, he does not have that right. Rather, he combines only Zuhr and 'Asr in the time of one of them, and Maghrib and 'Isha' in the time of one of them. As for Fajr, it is not combined with any other prayer; it is always prayed in its time, whether traveling or resident, before the sun rises, after the appearance of the dawn and before the sun rises. As for Zuhr and 'Asr, there is no harm in combining them before the sun turns yellow. He prays Zuhr with 'Asr after the time of 'Asr has entered, but before the sun turns yellow; he does not delay it. Or he brings 'Asr forward with Zuhr in travel, combining them by bringing the later prayer forward. This is how it is with Maghrib and 'Isha': either he brings 'Isha' forward with Maghrib and prays them after the time has entered, or he delays Maghrib and prays it with 'Isha' after the twilight has set and before the middle of the night. This is what is prescribed for Muslims. As for combining all of them at the end of the day, this is not permissible. Yes.
