عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُ أَنَّهُ كَانَ يَجْمَعُ بَيْنَ الصَّلَاتَيْنِ: الْمَغْرِبِ وَالْعِشَاءِ إِذَا غَابَ الشَّفَقُ، قَالَ: وَكَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَجْمَعُ بَيْنَهُمَا إِذَا جَدَّبَهُ السَّيْرُ، وَفِي رِوَايَةٍ: إِذَا جَدَّبَهُ السِّيْرُ إِلَى رُبُعِ اللَّيْلِ أَخَّرَهُمَا جَمِيعًا
Imam Nafi’ says: When the redness disappeared, Sayyiduna Abdullah bin Umar (may Allah be pleased with him) would combine Maghrib and Isha prayers and say: When the Messenger of Allah (peace and blessings be upon him) was in a hurry to travel, he would combine these two prayers. In another narration it is stated: When the Prophet (peace and blessings be upon him) was in a hurry to travel until a quarter of the night had passed, he would delay these two prayers.
