Sunan an-Nasa'i 4678
It was narrated the Abu Sa'eed Al-Khudri said:
"At the time of the Messenger of Allah, a man suffered loss of some fruit that he had purchased, and his debts increased. "The Messenger of Allah said: 'Give him charity.' So the people gave him charity, but that was not enough to pay off his debts. 'The Messenger of Allah said: 'Take what you find, but you have no right to more than that."' (meaning his creditors).
أَخْبَرَنَا أَحْمَدُ بْنُ عَمْرِو بْنِ السَّرْحِ، قَالَ أَنْبَأَنَا ابْنُ وَهْبٍ، قَالَ حَدَّثَنِي اللَّيْثُ بْنُ سَعْدٍ، وَعَمْرُو بْنُ الْحَارِثِ، عَنْ بُكَيْرِ بْنِ الأَشَجِّ، عَنْ عِيَاضِ بْنِ عَبْدِ اللَّهِ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ أُصِيبَ رَجُلٌ فِي عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم فِي ثِمَارٍ ابْتَاعَهَا وَكَثُرَ دَيْنُهُ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ تَصَدَّقُوا عَلَيْهِ ‏"‏ ‏.‏ فَتَصَدَّقُوا عَلَيْهِ وَلَمْ يَبْلُغْ ذَلِكَ وَفَاءَ دَيْنِهِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ خُذُوا مَا وَجَدْتُمْ وَلَيْسَ لَكُمْ إِلاَّ ذَلِكَ ‏"‏ ‏.‏
