(Imām Bukhārī narrates): Ali bin Abdullah narrated the hadith to us, he said: Sufyan narrated the hadith to us, he said: I heard az-Zuhri, from Salim, from his father, he said that
when the Prophet ﷺ had to go quickly, he ﷺ used to combine and offer the prayers of Maghrib and Isha.
حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، قَالَ حَدَّثَنَا سُفْيَانُ، قَالَ سَمِعْتُ الزُّهْرِيَّ، عَنْ سَالِمٍ، عَنْ أَبِيهِ، قَالَ
كَانَ النَّبِيُّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ يَجْمع بينَ المَغْرِبِ وَالعِشَاءِ إِذَا جَدَّ بِهِ السَّيْرُ
