Musnad Ahmad 410
‘Ata` bin Farrookh, the freed slave of the Qurashis, narrated that `Uthman (رضي الله عنه) bought some land from a man and the man did not seek payment for it. Then he met him and he said to him:
What prevented you from coming and taking your money? He said: You were unfair to me; I never met anyone but he blamed me. `Uthman said: Is this the reason? He said: Yes.  ‘Uthman said: Then choose between your land or your money. Then `Uthman said: The Messenger of Allah (ﷺ)  said: “Allah, may He be glorified and exalted, admitted to Paradise a man who was easygoing in buying and selling, when paying off debt and when asking for a debt that was owed to him.”
حَدَّثَنَا إِسْمَاعِيلُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا يُونُسُ يَعْنِي ابْنَ عُبَيْدٍ، حَدَّثَنِي عَطَاءُ بْنُ فَرُّوخَ، مَوْلَى الْقُرَشِيِّينَ أَنَّ عُثْمَانَ، رَضِيَ اللَّهُ عَنْهُ اشْتَرَى مِنْ رَجُلٍ أَرْضًا فَأَبْطَأَ عَلَيْهِ فَلَقِيَهُ فَقَالَ لَهُ مَا مَنَعَكَ مِنْ قَبْضِ مَالِكَ قَالَ إِنَّكَ غَبَنْتَنِي فَمَا أَلْقَى مِنْ النَّاسِ أَحَدًا إِلَّا وَهُوَ يَلُومُنِي قَالَ أَوَ ذَلِكَ يَمْنَعُكَ قَالَ نَعَمْ قَالَ فَاخْتَرْ بَيْنَ أَرْضِكَ وَمَالِكَ ثُمَّ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَدْخَلَ اللَّهُ عَزَّ وَجَلَّ الْجَنَّةَ رَجُلًا كَانَ سَهْلًا مُشْتَرِيًا وَبَائِعًا وَقَاضِيًا وَمُقْتَضِيًا‏.‏
