[Machine] He invited a Bedouin to his food, and that was after the Day of Sacrifice by a day. So the Bedouin said, "I am fasting." He said, "I have heard Abdullah bin Amr say, 'I have heard the Messenger of Allah ﷺ forbidding fasting on these days.'"  

الكبرى للنسائي:٢٩١١أَخْبَرَنَا مُحَمَّدُ بْنُ رَافِعٍ قَالَ حَدَّثَنَا عَبْدُ الرَّزَّاقِ قَالَ أَخْبَرَنَا مَعْمَرٌ عَنْ عَاصِمٍ عَنِ الْمُطَّلِبِ قَالَ

دَعَا أَعْرَابِيًّا إِلَى طَعَامِهِ وَذَلِكَ بَعْدَ يَوْمِ النَّحْرِ بِيَوْمٍ فَقَالَ الْأَعْرَابِيُّ إِنِّي صَائِمٌ فَقَالَ إِنِّي سَمِعْتُ عَبْدَ اللهِ بْنَ عَمْرٍو يَقُولُ إِنِّي سَمِعْتُ رَسُولَ اللهِ ﷺ «يَنْهَى عَنْ صِيَامِ هَذِهِ الْأَيَّامِ»
