The Messenger of Allah ﷺ forbade to sell grain which one buys by measurement until one receives it in full.  

أَنَّ رَسُولَ اللَّهِ ﷺ نَهَى أَنْ يَبِيعَ أَحَدٌ طَعَامًا اشْتَرَاهُ بِكَيْلٍ حَتَّى يَسْتَوْفِيَهُ  

Ibn ʿAbbas said, "Messenger of Allah ﷺ forbade the selling of foodstuff before its measuring and transferring into one's possession." I asked Ibn ʿAbbas, "How is that?" Ibn ʿAbbas replied, "It will be just like selling money for money, as the foodstuff has not been handed over to the first purchaser who is the present seller." (Using translation from Bukhārī 2132)  

أَنَّ رَسُولَ اللهِ ﷺ «نَهَى أَنْ يَبِيعَ الرَّجُلُ طَعَامًا حَتَّى يَسْتَوْفِيَهُ»
