Hadith 7:82
Muslim has:
"He gave permission regarding al-'Araya (for its sale) in which the household buys its fruit on the basis of a calculation (of what the dates would be when dry), yet they could eat them fresh (from the tree).
وَلِمُسْلِمٍ: { رَخَّصَ فِي اَلْعَرِيَّةِ يَأْخُذُهَا أَهْلُ اَلْبَيْتِ بِخَرْصِهَا تَمْرًا، يَأْكُلُونَهَا رُطَبًا }
