Hadith 22
وَلِلْحَاكِمِ فِي حَدِيثِ جَابِرٍ ‏- رضى الله عنه ‏- نَحْوُهُ, وَزَادَ فِي اَلَّذِي يُحَرِّمُ اَلطَّعَامَ: { إِنَّهُ يَذْهَبُ مُسْتَطِيلاً فِي اَلْأُفُقِ } وَفِي اَلْآخَرِ: { إِنَّهُ كَذَنَبِ اَلسِّرْحَان } 1‏ .‏
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."
