Narrated Al-Faji' ibn Abdullah al-Amiri:

Al-Faji' came to the Messenger of Allah ﷺ and asked: Is not dead meat lawful for us? He said: What is your food? We said: Some food in the evening and some in the morning. AbuNu'aym said: Uqbah explained it to me saying: a cup (of milk) in the morning and a cup in the evening; this does not satisfy the hunger. So made the carrion lawful for them in this condition.

Abu Dawud said: Ghabuq is a drink in the evening and Sabuh is a drink in the morning.

حَدَّثَنَا هَارُونُ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا الْفَضْلُ بْنُ دُكَيْنٍ، حَدَّثَنَا عُقْبَةُ بْنُ وَهْبِ بْنِ عُقْبَةَ الْعَامِرِيُّ، قَالَ سَمِعْتُ أَبِي يُحَدِّثُ، عَنِ الْفُجَيْعِ الْعَامِرِيِّ، أَنَّهُ أَتَى رَسُولَ اللَّهِ ﷺ فَقَالَ مَا يَحِلُّ لَنَا مِنَ الْمَيْتَةِ قَالَ " مَا طَعَامُكُمْ " . قُلْنَا نَغْتَبِقُ وَنَصْطَبِحُ . قَالَ أَبُو نُعَيْمٍ فَسَّرَهُ لِي عُقْبَةُ قَدَحٌ غُدْوَةً وَقَدَحٌ عَشِيَّةً . قَالَ " ذَاكَ - وَأَبِي - الْجُوعُ " . فَأَحَلَّ لَهُمُ الْمَيْتَةَ عَلَى هَذِهِ الْحَالِ . قَالَ أَبُو دَاوُدَ الْغَبُوقُ مِنْ آخِرِ النَّهَارِ وَالصَّبُوحُ مِنْ أَوَّلِ النَّهَارِ .
