[Machine] The Messenger of Allah ﷺ forbade "muzabanah" and "muzabanah" is when a person sells the dates of his palm tree by weight and sells his grapes by weight with raisins. This wording is from the hadith of Yahya ibn Yahya, and in the narration of Imam Shafi'i, may Allah have mercy on him, "muzabanah" is the sale of fruit by weight and the sale of grapes by weight with raisins.  

نَهَى رَسُولُ اللهِ ﷺ عَنِ الْمُزَابَنَةِ وَالْمُزَابَنَةُ أَنْ يَبِيعَ الرَّجُلُ ثَمَرَ نَخْلِهِ كَيْلًا وَكَرْمَهُ بِالزَّبِيبِ كَيْلًا هَذَا لَفْظُ حَدِيثِ يَحْيَى بْنِ يَحْيَى وَفِي رِوَايَةِ الشَّافِعِيِّ رَحِمَهُ اللهُ وَالْمُزَابَنَةُ بَيْعُ الثَّمَرِ بِالتَّمْرِ كَيْلًا وَبَيْعُ الْكَرْمِ بِالزَّبِيبِ كَيْلًا
