عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ، قَالَ: تُفْتَحُ أَبْوَابُ الْجَنَّةِ يَوْمَ الْإِثْنَيْنِ، وَيَوْمَ الْخَمِيسِ، فَيُغْفَرُ لِكُلِّ عَبْدٍ لَا يُشْرِكُ بِاللهِ شَيْئًا، إِلَّا رَجُلًا كَانَتْ بَيْنَهُ وَبَيْنَ أَخِيهِ شَحْنَاءُ، فَيُقَالُ: أَنْظِرُوا هَذَيْنِ حَتَّى يَصْطَلِحَا، أَنْظِرُوا هَذَيْنِ حَتَّى يَصْطَلِحَا، أَنْظِرُوا هَذَيْنِ حَتَّى يَصْطَلِحَا(باب النھي عن الشحناء و التهاجر)
Translation
Hazrat Abu Hurairah (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings of Allah be upon him) said: "The gates of Paradise are opened on Monday and Thursday, and every servant who does not associate anything with Allah is forgiven, except for a servant who has enmity with his brother. It is said: 'Give these two respite until they reconcile; give these two respite until they reconcile; give these two respite until they reconcile.' (And after reconciliation, they too will be forgiven.)"
