Hadith 1107

Narrated Ibn `Abbas:

Allah's Apostle used to offer the Zuhr and `Asr prayers together on journeys, and also used to offer the Maghrib and `Isha' prayers together. Narrated Anas bin Malik: The Prophet used to offer the Maghrib and the `Isha' prayers together on journeys.

وَقَالَ إِبْرَاهِيمُ بْنُ طَهْمَانَ عَنِ الْحُسَيْنِ الْمُعَلِّمِ، عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَجْمَعُ بَيْنَ صَلاَةِ الظُّهْرِ وَالْعَصْرِ إِذَا كَانَ عَلَى ظَهْرِ سَيْرٍ، وَيَجْمَعُ بَيْنَ الْمَغْرِبِ وَالْعِشَاءِ‏.‏
