(Imām Bukhārī narrates): Ishaq narrated the hadith to us, he said: Abdul Samad narrated the hadith to us, he said: Harb narrated the hadith to us, he said: Yahya narrated the hadith to us, he said: Hafs bin Ubaidullah bin Anas narrated the hadith to me, that Hazrat Anas (Allāh be pleased with him) narrated this hadith to him,
that the Messenger of Allāh ﷺ used to combine these two prayers while travelling, that is, Maghrib and Isha.
حَدَّثَنَا إِسْحَاقُ، حَدَّثَنَا عَبْدُ الصَّمَدِ بْنُ عَبْدِ الوَارِثِ، حَدَّثَنَا حَرْبٌ، حَدَّثَنَا يَحْيَى، قَالَ حَدَّثَنِي حَفْصُ بْنُ عُبَيْدِ اللَّهِ بْنِ أَنَسٍ، أَنَّ أَنَسًا رَضِيَ اللَّهُ عَنْهُ، حَدَّثَهُ
أَنَّ رَسُولَ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ كَانَ يَجْمَعُ بَينَ هَاتَيْنِ الصَّلاَتَيْنِ فِي السَّفَرِ ، يَعْنِي المَغْرِبَ وَالعِشَاءَ
