No other day is more unfortunate...
Al-Kāfi|Volume 8|Book 1|Chapter 492
عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ خَالِدٍ عَنْ عُثْمَانَ بْنِ عِيسَى عَنْ أَبِي أَيُّوبَ الْخَزَّازِ قَالَ أَرَدْنَا أَنْ نَخْرُجَ فَجِئْنَا نُسَلِّمُ عَلَى أَبِي عَبْدِ اللَّهِ (عليه السلام) فَقَالَ كَأَنَّكُمْ طَلَبْتُمْ بَرَكَةَ الْإِثْنَيْنِ فَقُلْنَا نَعَمْ فَقَالَ وَ أَيُّ يَوْمٍ أَعْظَمُ شُؤْماً مِنْ يَوْمِ الْإِثْنَيْنِ يَوْمٍ فَقَدْنَا فِيهِ نَبِيَّنَا وَ ارْتَفَعَ الْوَحْيُ عَنَّا لَا تَخْرُجُوا وَ اخْرُجُوا يَوْمَ الثَّلَاثَاءِ.
492. A number of our companions, from Ahmad bin Muhammad bin Khalid, from Uthman bin Isa, from Abu Ayyub Al-Khazzaaz who said: We intended to go out, so we went to greet Abu Abdullah عليه السلام. So he عليه السلام said: ‘It is as if you all are seeking blessings on Monday’. So we said, ‘Yes’. So he عليه السلام said: ‘No other day is of great misfortune than a Monday, the day in which we lost our Prophet صلى الله عليه وعلى آله وسلم, and the revelation was raised (stopped) from us. Do not go out (on a Monday), and go out on a Tuesday’.
