عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ اِبْنِ أَبِي عُمَيْرٍ عَنْ عَلِيِّ بْنِ عَطِيَّةَ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ:« اَلصُّبْحُ هُوَ اَلَّذِي إِذَا رَأَيْتَهُ مُعْتَرِضاً كَأَنَّهُ بَيَاضُ سُورَاءَ»
Narrated by Ali ibn Ibrahim from his father from Ibn Abi ‘Umayr from Ali ibn ‘Atiyyah:
Abu Abdillah عليه السلام said: "The Subh (morning) is that which, when you see it spreading horizontally, it is as if it were the whiteness of a stream."
