The Messenger of Allah ﷺ observed the noon and afternoon prayers together, and the sunset and Isha' prayers together without being in a state of fear or in a state of journey.  

صَلَّى رَسُولُ اللَّهِ ﷺ الظُّهْرَ وَالْعَصْرَ جَمِيعًا وَالْمَغْرِبَ وَالْعِشَاءَ جَمِيعًا فِي غَيْرِ خَوْفٍ وَلاَ سَفَرٍ  

We set out with the Messenger of Allah ﷺ on the Tabuk expedition, and he observed the noon and afternoon prayers together and the sunset and 'Isha' prayers together.  

خَرَجْنَا مَعَ رَسُولِ اللَّهِ ﷺ فِي غَزْوَةِ تَبُوكَ فَكَانَ يُصَلِّي الظُّهْرَ وَالْعَصْرَ جَمِيعًا وَالْمَغْرِبَ وَالْعِشَاءَ جَمِيعًا  

[Machine] "We accompanied the Messenger of Allah ﷺ on the expedition of Tabuk. He used to combine the Dhuhr and Asr prayers, praying them together. Then, he entered (a place) and after that he came out again and prayed the Maghrib and Isha prayers together."  

خَرَجْنَا مَعَ رَسُولِ اللَّهِ ﷺ عَامَ غَزْوَةِ تَبُوكَ فَكَانَ يَجْمَعُ الصَّلَاةَ يَصَلَّى الظُّهْرَ وَالْعَصْرَ جَمِيعًا ثُمَّ دَخَلَ ثُمَّ خَرَجَ بَعْدَ ذَلِكَ فَصَلَّى الْمَغْرِبَ وَالْعِشَاءَ جَمِيعًا  

"The Messenger of Allah ﷺ prayed Zuhr and 'Asr together, and Maghrib and 'Isha' together, when there was no fear and he was not traveling." (Using translation from Nasāʾī 601)  

«صَلَّى رَسُولُ اللَّهِ ﷺ الظُّهْرَ وَالْعَصْرَ جَمِيعًا وَالْمَغْرِبَ وَالْعِشَاءَ جَمِيعًا فِي غَيْرِ خَوْفٍ وَلَا سَفَرٍ»  

We set out with the Messenger of Allah ﷺ on the Tabuk expedition, and he observed the noon and afternoon prayers together and the sunset and 'Isha' prayers together. (Using translation from Muslim 706a)  

«خَرَجْنَا مَعَ النَّبِيِّ ﷺ فِي غَزْوَةِ تَبُوكٍ وَكَانَ يُصَلِّي الظُّهْرَ وَالْعَصْرَ جَمِيعًا وَالْمَغْرِبَ وَالْعِشَاءَ جَمِيعًا»  

" جَمَعَ النَّبِىُّ ﷺ فِى غَزْوَةِ تَبُوكَ بَيْنَ الظُّهْرِ وَالْعَصْرِ، وبَيْنَ الْمَغْرِبِ وَالْعشَاءِ ".
