BAYHAQI 19219:
from Nubayshah —
[Machine] The Messenger of Allah ﷺ said: "We used to prohibit you from eating its meat for more than three days, so that it would be enough for you. Then Allah brought abundance, so eat, save, and do business. Behold, these days are days of eating, drinking, and remembering Allah. And when he said 'and do business,' he meant to maintain kinship by giving gifts, for charity sought for its reward, not for trade."
البيهقي ١٩٢١٩:
عن نبيسهه —
قَالَ رَسُولُ اللهِ ﷺ إِنَّا كُنَّا نَهَيْنَاكُمْ عَنْ لُحُومِهَا أَنْ تَأْكُلُوهَا فَوْقَ ثَلَاثٍ لِكَيْ يَسَعَكُمْ جَاءَ اللهُ بِالسَّعَةِ فَكُلُوا وَادَّخِرُوا وَاتَّجِرُوا أَلَا وَإِنَّ هَذِهِ الْأَيَّامَ أَيَّامُ أَكْلٍ وَشُرْبٍ وَذِكْرِ اللهِ ﷻ قَوْلُهُ وَاتَّجِرُوا صِلَةُ ائْتَجِرُوا عَلَى وَزْنِ افْتَعِلُوا يُرِيدُ الصَّدَقَةَ الَّتِي يُبْتَغَى أَجْرُهَا وَلَيْسَ مِنْ بَابِ التِّجَارَةِ
