The ruling on combining prayers for the traveler

Question:
If a person is traveling, is it permissible for him to combine the prayers?

Answer:
If shortening the prayer is prescribed for him, then he combines the prayers. If the state of travel permits shortening, it permits combining, especially when the Shaykh is on the road; he shortens and combines, either by delaying or by advancing, according to his situation. However, if he stops during the journey, stops on the road, and the prayer times come upon him while he is stopped, he prays each prayer in its time without combining. He prays each prayer in its time, shortened, without combining, as the Prophet (peace and blessings be upon him) did in Mina during the days of Tashriq. The Prophet (peace and blessings be upon him) shortened the prayer but did not combine; he prayed each prayer in its time. Combining is for the state of travel and shortening. This is the best. But if he combines while stopped, it is permissible, though the first prayer is better. It is better that he pray each prayer in its time with shortening. Yes.
