Chapter 18 | What Is Dawn, When Does It Come and When Is It Unlawful to Eat?
2ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ عَلِيِّ بْنِ عَطِيَّةَ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ الْفَجْرُ هُوَ الَّذِي إِذَا رَأَيْتَهُ مُعْتَرِضاً كَأَنَّهُ بَيَاضُ سُورَى.
2. Ali ibn Ibrahim has narrated from his father from Ali ibn ‘ Atiyyah who has said the following: “Abu ‘Abd Allah , has said, ‘Dawn is when you see it, widthwise, like the whiteness of the suray (canal) (Euphrates river).”’
