It was narrated from Mujahid, Sa’eed bin Jubair, ‘Ata’ bin Abi Rabah and Tawus that Ibn ‘Abbas told them that the Messenger of Allah ﷺ used to combine the Maghrib and ‘Isha’ when traveling, although there was nothing to make him hurry and no enemy pursuing him, and he was not afraid of anything.
أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَجْمَعُ بَيْنَ الْمَغْرِبِ وَالْعِشَاءِ فِي السَّفَرِ مِنْ غَيْرِ أَنْ يُعْجِلَهُ شَىْءٌ وَلاَ يَطْلُبَهُ عَدُوٌّ وَلاَ يَخَافَ شَيْئًا
[Machine] That the Messenger of Allah ﷺ used to combine between the noon and afternoon prayers, and combine between the sunset and evening prayers while traveling, without any necessity or fear from an enemy.
أَنَّ رَسُولَ اللهِ ﷺ «كَانَ يَجْمَعُ بَيْنَ الظُّهْرِ وَالْعَصْرِ وَيَجْمَعُ بَيْنَ الْمَغْرِبِ وَالْعِشَاءِ فِي السَّفَرِ مِنْ غَيْرِ أَنْ يُعَجِّلَهُ أَمْرٌ أَوْ يَطْلُبَهُ عَدُوٌّ أَوْ يَخَافَ شَيْئًا»
"عَنْ أنَسٍ: أنَّ رَسُولَ الله ﷺ كَانَ يَجْمَعُ بَيْنَ المَغْرِبِ وَالعِشَاءِ في السَّفَرِ".
