[Machine] The Messenger of Allah ﷺ established the prayers of Dhuhr and Asr for both residents and travelers. So, just as you pray before and after Dhuhr in normal circumstances, pray before and after it while traveling. Waki' reported once to pray it while traveling.
فَرَضَ رَسُولُ اللهِ ﷺ صَلاةَ الْحَضَرِ وَالسَّفَرِ فَكَمَا تُصَلِّي فِي الْحَضَرِ قَبْلَهَا وَبَعْدَهَا فَصَلِّ فِي السَّفَرِ قَبْلَهَا وَبَعْدَهَا قَالَ وَكِيعٌ مَرَّةً وَصَلِّهَا فِي السَّفَرِ
“I asked Tawus about performing voluntary prayer while traveling. Al-Hasan bin Muslim bin Yannaq was sitting with him and he said: ‘Tawus told me that he heard Ibn ‘Abbas say: “The Messenger of Allah ﷺ enjoined prayer while a resident and prayer when one is traveling. We used to pray when we were residents both before and after (the obligatory prayer), and we used to pray both before and after (the obligatory prayer) when we were traveling.’”
أَنَّهُ سَمِعَ ابْنَ عَبَّاسٍ يَقُولُ فَرَضَ رَسُولُ اللَّهِ ﷺ صَلاَةَ الْحَضَرِ وَصَلاَةَ السَّفَرِ فَكُنَّا نُصَلِّي فِي الْحَضَرِ قَبْلَهَا وَبَعْدَهَا وَكُنَّا نُصَلِّي فِي السَّفَرِ قَبْلَهَا وَبَعْدَهَا
