the Prophet annulled transaction in the event of crop faioure. (Using translation from Nasāʾī 4529)   

«أَنَّ النَّبِيَّ ﷺ أَمَرَ بِوَضْعِ الْجَوَائِحِ»  

[Machine] A woman entered upon the Prophet ﷺ and said, "By my father and mother, I and my son bought something from so-and-so and we weighed it. By the One who honored you with what He honored you with, we did not take anything from it except what we ate in our stomachs or fed to a needy person, hoping for blessings. And we have been setting aside what we owe from it until we receive the complete amount." Then the Prophet ﷺ took an oath by Allah three times, saying, "He who does not act with righteousness will not be successful." The news reached the owner of the merchandise, and he said, "By my father and mother, if you wish, I will return what you are owed, and if you wish, I will donate from the capital."  

دَخَلَتِ امْرَأَةٌ عَلَى النَّبِيِّ ﷺ فَقَالَتْ بِأَبِي وَأُمِّي إِنِّي ابْتَعْتُ أَنَا وَابْنِي مِنْ فُلَانٍ ثَمَرَ مَالِهِ فَأَحْصَيْنَاهُ لَا وَالَّذِي أَكْرَمَكَ بِمَا أَكْرَمَكَ بِهِ مَا أَحْصَيْنَا مِنْهُ شَيْئًا إِلَّا شَيْئًا نَأْكُلُهُ فِي بُطُونِنَا أَوْ نُطْعِمُ مِسْكِينًا رَجَاءَ الْبَرَكَةِ وَجِئْنَا نَسْتَوْضِعُهُ مَا نَقَصْنَا فَحَلَفَ بِاللَّهِ لَا يَضَعُ لَنَا شَيْئًا فَقَالَ نَبِيُّ اللَّهِ ﷺ «تَأَلَّى لَا يَصْنَعُ خَيْرًا» ثَلَاثَ مَرَّاتٍ قَالَتْ فَبَلَغَ ذَلِكَ صَاحِبَ الثَّمَرِ فَقَالَ بِأَبِي وَأُمِّي إِنْ شِئْتَ وَضَعْتُ مَا نَقَصُوا وَإِنْ شِئْتَ مِنْ رَأْسِ الْمَالِ فَوَضَعَ مَا نَقَصُوا  

In the time of the Messenger of Allah ﷺ a man suffered loss affecting fruits he had bought and owed a large debt, so the Messenger of Allah ﷺ said: Give him sadaqah (alms). So the people gave him sadaqah (alms), but as that was not enough to pay the debt in full, the Messenger of Allah ﷺ said: Take what you find. But that is all you may have. (Using translation from Abū Dāʾūd 3469)  

أَنَّهُ قَالَ أُصِيبَ رَجُلٌ فِي عَهْدِ رَسُولِ اللَّهِ ﷺ فِي ثِمَارٍ ابْتَاعَهَا فَكَثُرَ دَيْنُهُ فَقَالَ رَسُولُ اللَّهِ ﷺ «تَصَدَّقُوا عَلَيْهِ» فَتُصُدِّقَ عَلَيْهِ فَلَمْ يَبْلُغْ ذَلِكَ وَفَاءَ دَيْنِهِ فَقَالَ رَسُولُ اللَّهِ ﷺ «خُذُوا مَا وَجَدْتُمْ وَلَيْسَ لَكُمْ إِلَّا ذَلِكَ»  

The Messenger of Allah ﷺ as saying: If you were to sell dried dates to your brother and they were smitten by blight, it will not be allowable for you to take your brother's property unjustly. (Using translation from Abū Dāʾūd 3470)   

قَالَ رَسُولُ اللَّهِ ﷺ «إِنْ بِعْتَ مِنْ أَخِيكَ ثَمَرًا فَأَصَابَتْهُ جَائِحَةٌ فَلَا يَحِلُّ لَكَ أَنْ تَأْخُذَ مِنْهُ شَيْئًا بِمَ تَأْخُذُ مِنْ مَالِ أَخِيكَ بِغَيْرِ حَقٍّ؟ » قُلْتُ لِأَبِي الزُّبَيْرِ هَلْ سَمَّى لَكُمُ الْجَوَائِحَ؟ قَالَ لَا
