Sunan an-Nasai
أَخْبَرَنَا مُحَمَّدُ بْنُ سَلَمَةَ، وَالْحَارِثُ بْنُ مِسْكِينٍ، قِرَاءَةً عَلَيْهِ وَأَنَا أَسْمَعُ، - وَاللَّفْظُ لَهُ - عَنِ ابْنِ الْقَاسِمِ، قَالَ حَدَّثَنِي مَالِكٌ، عَنْ أَبِي الزُّبَيْرِ الْمَكِّيِّ، عَنْ أَبِي الطُّفَيْلِ، عَامِرِ بْنِ وَاثِلَةَ أَنَّ مُعَاذَ بْنَ جَبَلٍ، أَخْبَرَهُ أَنَّهُمْ، خَرَجُوا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم عَامَ تَبُوكَ فَكَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَجْمَعُ بَيْنَ الظُّهْرِ وَالْعَصْرِ وَالْمَغْرِبِ وَالْعِشَاءِ فَأَخَّرَ الصَّلاَةَ يَوْمًا ثُمَّ خَرَجَ فَصَلَّى الظُّهْرَ وَالْعَصْرَ جَمِيعًا ثُمَّ دَخَلَ ثُمَّ خَرَجَ فَصَلَّى الْمَغْرِبَ وَالْعِشَاءَ .
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'.
