وَلِلْحَاكِمِ فِي حَدِيثِ جَابِرٍ - رضى الله عنه - نَحْوُهُ, وَزَادَ فِي اَلَّذِي يُحَرِّمُ اَلطَّعَامَ: «إِنَّهُ يَذْهَبُ مُسْتَطِيلاً فِي اَلْأُفُقِ» وَفِي اَلْآخَرِ: «إِنَّهُ كَذَنَبِ اَلسِّرْحَان»
al-Hakim reported something similar to the above Hadith from Jabir and added to the type of dawn in which eating is forbidden:
“it is spread widely in the horizon,” and to the other type: “it has the shape of wolf's tail.”
