Sacrifice (Kitab Al-Dahaya)
Dawud :: Book 15 : Hadith 2807
Narrated Nubayshah:
The Prophet (peace_be_upon_him) said: We forbade you to eat their meat for more than three days in order that you might have abundance; now Allah has produced abundance, so you may eat, store up and seek reward. Beware, these days are days of eating, drinking and remembrance of Allah, Most High.
