It was narrated from Mujahid, Sa’eed bin Jubair, ‘Ata’ bin Abi Rabah and Tawus that Ibn ‘Abbas told them that the Messenger of Allah ﷺ used to combine the Maghrib and ‘Isha’ when traveling, although there was nothing to make him hurry and no enemy pursuing him, and he was not afraid of anything.  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَجْمَعُ بَيْنَ الْمَغْرِبِ وَالْعِشَاءِ فِي السَّفَرِ مِنْ غَيْرِ أَنْ يُعْجِلَهُ شَىْءٌ وَلاَ يَطْلُبَهُ عَدُوٌّ وَلاَ يَخَافَ شَيْئًا  

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.  

أَنَّ النَّبِيَّ ﷺ جَمَعَ بَيْنَ الظُّهْرِ وَالْعَصْرِ وَالْمَغْرِبِ وَالْعِشَاءِ فِي غَزْوَةِ تَبُوكَ فِي السَّفَرِ
