حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ وَأَبُو دَاوُدَ عَنْ شُعْبَةَ عَنْ أَبِي إِسْحَاقَ عَنْ عَمْرِو بْنِ مَيْمُونٍ قَالَ صَلَّى عُمَرُ رَضِيَ اللَّهُ عَنْهُ الصُّبْحَ وَهُوَ بِجَمْعٍ قَالَ أَبُو دَاوُدَ كُنَّا مَعَ عُمَرَ بِجَمْعٍ فَقَالَ إِنَّ الْمُشْرِكِينَ كَانُوا لَا يُفِيضُونَ حَتَّى تَطْلُعَ الشَّمْسُ وَيَقُولُونَ أَشْرِقْ ثَبِيرُ وَإِنَّ نَبِيَّ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خَالَفَهُمْ فَأَفَاضَ قَبْلَ طُلُوعِ الشَّمْسِ
مسند امام احمد بن حنبل · Hadith 358
It was narrated that 'Amr bin Maimoon said: 'Umar (RA) prayed Fajr when he was in Jam'. Abu Da wood said: We were with 'Umar in Jam', and he said: The mushrikoon used not to move on until the sun rose, and they would say: Shine, (Mount) Thabeer. The Prophet of Allah (PBUH) differed from them and moved on before the sun rose.
