Narrated Mu'adh bin Jabal (RA):

We went out with Allah's Messenger (ﷺ) on the Tabuk expedition, and he would offer Zuhr and 'Asr prayers together and Magbrib and 'Isha' prayers together. [Reported by Muslim].

وَعَنْ مُعَاذٍ ‏- رضى الله عنه ‏- قَالَ: { خَرَجْنَا مَعَ رَسُولِ اَللَّهِ ‏- صلى الله عليه وسلم ‏-فِي غَزْوَةِ تَبُوكَ، فَكَانَ يُصَلِّي اَلظُّهْرَ وَالْعَصْرَ جَمِيعًا, وَالْمَغْرِبَ وَالْعِشَاءَ جَمِيعًا } رَوَاهُ مُسْلِمٌ .‏ [1]‏ .‏
