So I returned to them and informed them, and it seemed as if they denied it. So they all went to her and said, "We sent this to you about so and so and you mentioned that you said so and so." She said, "Yes, it is true that the Messenger of Allah ﷺ used to fast the most on the days of Saturday and Sunday, and he used to say, 'They are the days of celebration for the polytheists and I want to differ from them.'"
أَخْبَرَهُ أَنَّ ابْنَ عَبَّاسٍ وَنَاسًا مِنْ أَصْحَابِ الرَّسُولِ ﷺ بَعَثُونِي إِلَى أُمِّ سَلَمَةَ أَسْأَلُهَا عَنْ أَيِّ الْأَيَّامِ كَانَ رَسُولُ اللَّهِ ﷺ أَكْثَرَ لَهَا صِيَامًا؟ فَقَالَتْ يَوْمُ السَّبْتِ وَالْأَحَدِ فَرَجَعْتُ إِلَيْهِمْ فَأَخْبَرْتُهُمْ فَكَأَنَّهُمْ أَنْكَرُوا ذَلِكَ فَقَامُوا بِأَجْمَعِهِمْ إِلَيْهَا فَقَالُوا إِنَّا بَعَثْنَا إِلَيْكِ هَذَا فِي كَذَا وَكَذَا فَذَكَرَ أَنَّكِ قُلْتِ كَذَا وَكَذَا فَقَالَتْ صَدَقَ إِنَّ رَسُولَ اللَّهِ ﷺ أَكْثَرَ مَا كَانَ يَصُومُ مِنَ الْأَيَّامِ يَوْمُ السَّبْتِ وَالْأَحَدِ وَكَانَ يَقُولُ «إِنَّهُمَا يَوْمَا عِيدٍ لِلْمُشْرِكِينَ وَأَنَا أُرِيدُ أَنْ أُخَالِفَهُمْ»
