عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ
أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: تُفْتَحُ أَبْوَابُ الْجَنَّةِ يَوْمَ الِاثْنَيْنِ، وَيَوْمَ الْخَمِيسِ، فَيُغْفَرُ لِكُلِّ عَبْدٍ لَا يُشْرِكُ بِاللَّهِ شَيْئًا، إِلَّا رَجُلًا كَانَتْ بَيْنَهُ وَبَيْنَ أَخِيهِ شَحْنَاءُ، فَيُقَالُ: (1) أَنْظِرُوا (2) هَذَيْنِ حَتَّى يَصْطَلِحَا، أَنْظِرُوا هَذَيْنِ حَتَّى يَصْطَلِحَا، أَنْظِرُوا هَذَيْنِ حَتَّى يَصْطَلِحَا
The Messenger of Allah (sallallahu alayhi wa sallam) said: The gates of Paradise will be opened on Mondays and on Thursdays, and every servant [of Allah] who associates nothing with Allah will be forgiven, except for the man who has a grudge against his brother. [About them] it will be said: Delay these two until they are reconciled; delay these two until they are reconciled. It was related by Muslim (also by Malik and Abu Dawud).
