It was narrated from Abu At-Tufail 'Amir bin Wathilah that Mu'adh bin Jabal told him that they went out with the Messenger of Allah ﷺ in the year of Tabuk, and the Messenger of Allah ﷺ was joining Zuhr and 'Asr, and Maghrib and 'Isha'. He delayed the prayer one day then he went out and prayed Zuhr and 'Asr together, then he went in and came out again and prayed Maghrib and 'Isha'. (Using translation from Nasāʾī 587)
أَخْبَرَهُ أَنَّهُمْ خَرَجُوا مَعَ رَسُولِ اللهِ ﷺ عَامَ تَبُوكَ فَكَانَ رَسُولُ اللهِ ﷺ «يَجْمَعُ بَيْنَ الظُّهْرِ وَالْعَصْرِ وَالْمَغْرِبِ وَالْعِشَاءِ فَأَخَّرَ الصَّلَاةَ يَوْمًا ثُمَّ خَرَجَ فَصَلَّى الظُّهْرَ وَالْعَصْرَ جَمِيعًا ثُمَّ دَخَلَ ثُمَّ خَرَجَ فَصَلَّى الْمَغْرِبَ وَالْعِشَاءَ جَمِيعًا»
