The Prophet ﷺ forbade selling fruits years ahead, and commanded that unforeseen loss be remitted in respect of what is affected by blight. Abu Dawud said: The attribution of the tradition regarding the effect of blight is one-third of the produce to the Prophet ﷺ is not correct. This is the opinion of the people of Medina.  

أَنَّ النَّبِيَّ ﷺ نَهَى عَنْ بَيْعِ السِّنِينَ وَوَضَعَ الْجَوَائِحَ  

The Prophet ﷺ forbade sale of fruits for a number of years. One of the two narrators (Abu al-Zubair and Sa'id b. Mina') mentioned the words "sale for years" (bai' al-sinin instead of al-mu'awamah).  

أَنَّ النَّبِيَّ ﷺ نَهَى عَنِ الْمُعَاوَمَةِ وَقَالَ أَحَدُهُمَا بَيْعِ السِّنِينَ
