Hazrat Abu Hurairah (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings of Allah be upon him) said:
تُعْرَضُ أَعْمَالُ النَّاسِ فِي كُلِّ جُمُعَةٍ مَرَّتَيْنِ يَوْمَ الاِثْنَيْنِ وَيَوْمَ الْخَمِيسِ فَيُغْفَرُ لِكُلِّ عَبْدٍ مُؤْمِنٍ إِلَّا عَبْدًا بَيْنَهُ وَبَيْنَ أَخِيهِ شَحْنَاءُ فَيُقَالُ اتْرُكُوا أَوِ ارْكُوا هَذَيْنِ حَتَّى يَفِيئَا .
“The people’s deeds are presented every week, on Thursday and Monday, and Allah, and every believing servant would be granted pardon except the one in whose heart there is rancour against his brother and it would be said, ‘Leave them and put them off until they are reconciled.’”
[Sahih Muslim, 2565d]
