النسائي:٢١٧٤ – أَخْبَرَنَا مُحَمَّدُ بْنُ الْعَلاَءِ قَالَ حَدَّثَنَا أَبُو خَالِدٍ عَنْ مُحَمَّدِ بْنِ عَمْرٍو عَنْ أَبِي سَلَمَةَ عَنِ ابْنِ عَبَّاسٍ قَالَ

قَالَ رَسُولُ اللَّهِ ﷺ لاَ تَتَقَدَّمُوا الشَّهْرَ بِصِيَامِ يَوْمٍ وَلاَ يَوْمَيْنِ إِلاَّ أَنْ يُوَافِقَ ذَلِكَ يَوْمًا كَانَ يَصُومُهُ أَحَدُكُمْ قَالَ أَبُو عَبْدِ الرَّحْمَنِ هَذَا خَطَأٌ
