باب اسْتِحْبَابِ صِيَامِ ثَلَاثَةِ أَيَّامٍ مِنْ كُلِّ شَهْرٍ وَصَوْمِ يَوْمِ عَرَفَةَ وَعَاشُورَاءَ وَالِاثْنَيْنِ وَالْخَمِيسِ

Sahih Muslim 1162d
وَحَدَّثَنِي أَحْمَدُ بْنُ سَعِيدٍ الدَّارِمِيُّ، حَدَّثَنَا حَبَّانُ بْنُ هِلاَلٍ، حَدَّثَنَا أَبَانُ الْعَطَّارُ، حَدَّثَنَا غَيْلاَنُ بْنُ جَرِيرٍ، فِي هَذَا الإِسْنَادِ بِمِثْلِ حَدِيثِ شُعْبَةَ غَيْرَ أَنَّهُ ذَكَرَ فِيهِ الاِثْنَيْنِ وَلَمْ يَذْكُرِ الْخَمِيسَ ‏.‏
This hadith has been narrated by Ghailan b. Jarir with the same chain of transmitters, but with one variation, that there has been made mention of Monday and not of Thursday.
