وَعَنْ جَابِرٍ قَالَ: نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ بَيْعِ السِّنِينَ وَأَمَرَ بوضْعِ الجوائحِ. رَوَاهُ مُسلم
Jabir said that God's Messenger forbade selling fruit years ahead, and commanded that unforeseen loss be remitted in respect of what is affected by blight. Muslim transmitted it.
