عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ كَانَ أَكْثَرَ مَا يَصُومُ الْإِثْنَيْنِ وَالْخَمِيسَ، قَالَ: فَقِيلَ لَهُ، قَالَ: ((إِنَّ الْأَعْمَالَ تُعْرَضُ كُلَّ اثْنَيْنِ وَخَمِيسٍ أَوْ كُلَّ يَوْمِ اثْنَيْنِ وَخَمِيسٍ فَيَغْفِرُ اللَّهُ لِكُلِّ مُسْلِمٍ أَوْ لِكُلِّ مُؤْمِنٍ إِلَّا الْمُتَهَاجِرَيْنِ، فَيَقُولُ: أَخِّرْهُمَا))
It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) used to fast frequently on Mondays and Thursdays. When he (peace and blessings be upon him) was asked about this, he (peace and blessings be upon him) said: The deeds of people are presented before Allah Almighty on Mondays and Thursdays, and Allah Almighty forgives every Muslim or every believer, except for two men between whom there is a severance of relations. Regarding them, Allah Almighty says: Defer their matter.
