Is it better to shorten and combine prayers, or only shorten them, while traveling?

Question:
Abu al-Ghayth says in this question: Honorable Shaykh, regarding prayer while traveling, is it permissible for a traveler to shorten the obligatory prayer, for example, to pray the midday prayer in its time as two units, and then wait until the time for the afternoon prayer enters, and then pray that as two units as well? Or does he combine the midday and afternoon prayers as two units each?

Answer:
If he is in the midst of travel, he combines and shortens, because that is more convenient for him, whether combining by bringing forward or combining by delaying. But if he has stopped during his journey for rest or to attend to a need, he shortens without combining; this is what is best. The Prophet (peace and blessings be upon him) was in Mina during the days of Hajj, and he would pray every prayer in its time, shortened, without combining. Yes.
