Salim reported from his father to be saying:I saw the Messenger of Allah (ﷺ) combining the sunset and Isha' prayers when he was in a hurry on a journey
رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم إِذَا أَعْجَلَهُ السَّيْرُ فِي السَّفَرِ يُؤَخِّرُ صَلاَةَ الْمَغْرِبِ حَتَّى يَجْمَعَ بَيْنَهَا وَبَيْنَ صَلاَةِ الْعِشَاءِ.
Salim b. 'Abdullah reported that his father had said:I saw the Messenger of Allah (ﷺ) delaying the sunset prayer till he would combine it with the 'Isha' when he hastened to set out on a journey
