Full Sharh — Al-Adab Al-Mufrad 413
حَدَّثَنَا إِسْمَاعِيلُ قَالَ: حَدَّثَنِي مَالِكٌ، عَنْ سُهَيْلٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللهِ صلى الله عليه وسلم قَالَ: تُفْتَحُ أَبْوَابُ الْجَنَّةِ يَوْمَ الِاثْنَيْنِ وَيَوْمَ الْخَمِيسِ، فَيُغْفَرُ لِكُلِّ عَبْدٍ لاَ يُشْرِكُ بِاللَّهِ شَيْئًا، إِلاَّ رَجُلٌ كَانَتْ بَيْنَهُ وَبَيْنَ أَخِيهِ شَحْنَاءُ، فَيُقَالُ: أَنْظِرُوا هَذَيْنِ حَتَّى يَصْطَلِحَا.
English Translation
Abu Hurayra reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "The gates of the Garden are opened on Mondays and Thursdays. Every person who does not associate anything with Allah is forgiven except for someone who has enmity between existing between him and another man. It is said, 'Leave these two until they make peace.'"
