It was narrated from Mu’adh bin Jabal that the Prophet ﷺ combined the Zuhr and ‘Asr, and the Maghrib and ‘Isha’ when traveling during the campaign of Tabuk. (Using translation from Ibn Mājah 1070)
أَنَّ النَّبِيَّ ﷺ جَمَعَ بَيْنَ الظُّهْرِ وَالْعَصْرِ وَالْمَغْرِبِ وَالْعِشَاءِ فِي غَزْوَةِ تَبُوكَ
