Mishkat al-Masabih 10 The Rites of Pilgrimage كتاب المناسك 136

وَعَنْ نُبَيْشَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صلى الله عَلَيْهِ وَسلم: «إِن كُنَّا نهينَا عَنْ لُحُومِهَا أَنْ تَأْكُلُوهَا فَوْقَ ثَلَاثٍ لِكَيْ تسَعْكم. جاءَ اللَّهُ بالسَّعَةِ فكُلوا وادَّخِرُوا وأْتَجِروا. أَلَا وَإِنَّ هَذِهِ الْأَيَّامَ أَيَّامُ أَكْلٍ وَشُرْبٍ وذِكْرِ اللَّهِ» . رَوَاهُ أَبُو دَاوُد

Nubaisha reported God’s messenger as saying, “I forbade you to eat their meat for more than three days in order that you might have abundance [for charity] ; but God has produced abundance, so you may eat, store up and seek reward. These days are days of eating, drinking and remembrance of God.” Abu Dawud transmitted it.
