وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: مَنْ كَانَتْ عِنْدَهُ مَظْلَمَةٌ لأَخِيهِ، من عرضه أو من شيء، فَلْيَتَحَلَّلْهُ مِنْهُ الْيَوْمَ قَبْلَ أَنْ لاَ يَكُونَ دِينَارٌ وَلاَ دِرْهَمٌ ، إِنْ كَانَ لَهُ عَمَلٌ صَالِحٌ أُخِذَ مِنْهُ بِقَدْرِ مَظْلَمَتِهِ، وَإِنْ لَمْ يَكُنْ لَهُ حَسَنَاتٌ أُخِذَ مِنْ سَيِّئَاتِ صاحبه فحمل عَلَيْهِ ((رَوَاهُ الْبُخَارِيّ)).
Abu Hurairah (May Allah bepleased with him) reported: The Prophet (ﷺ) said, "He who has done a wrong affecting his brother's honour or anything else, let him ask his forgiveness today before the time (i.e., the Day of Resurrection) when he will have neither a dinar nor a dirham. If he has done some good deeds, a portion equal to his wrong doings will be subtracted from them; but if he has no good deeds, he will be burdened with the evil deeds of the one he had wronged in the same proportion". [Al-Bukhari].
