Sahih Bukhari Volume 8, Book 81, Hadith 6536

حَدَّثَنَا إِسْمَاعِيلُ، قَالَ حَدَّثَنِي مَالِكٌ، عَنْ سَعِيدٍ الْمَقْبُرِيِّ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ مَنْ كَانَتْ عِنْدَهُ مَظْلَمَةٌ لأَخِيهِ فَلْيَتَحَلَّلْهُ مِنْهَا، فَإِنَّهُ لَيْسَ ثَمَّ دِينَارٌ وَلاَ دِرْهَمٌ مِنْ قَبْلِ أَنْ يُؤْخَذَ لأَخِيهِ مِنْ حَسَنَاتِهِ، فَإِنْ لَمْ يَكُنْ لَهُ حَسَنَاتٌ أُخِذَ مِنْ سَيِّئَاتِ أَخِيهِ، فَطُرِحَتْ عَلَيْهِ ‏"‏‏.‏

Narrated By Abu Huraira : Allah's Apostle said, "Whoever has wronged his brother, should ask for his pardon (before his death), as (in the Hereafter) there will be neither a Dinar nor a Dirham. (He should secure pardon in this life) before some of his good deeds are taken and paid to his brother, or, if he has done no good deeds, some of the bad deeds of his brother are taken to be loaded on him (in the Hereafter)."
