The Prophet ﷺ 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. (Using translation from Abū Dāʾūd 2813)
عَنْ نُبَيْشَةَ قَالَ قَالَ رَسُولُ اللهِ ﷺ إِنَّا كُنَّا نَهَيْنَاكُمْ أَنْ تَأْكُلُوا لُحُومَهَا فَوْقَ ثَلَاثٍ كَيْ يَسَعَكُمْ فَقَدْ جَاءَ اللهُ بِالسَّعَةِ فَكُلُوا وَادَّخِرُوا وَاتَّجِرُوا أَلَا وَإِنَّ هَذِهِ الْأَيَّامَ أَيَّامُ أَكْلٍ وَشُرْبٍ وَذِكْرِ اللهِ
