Narrated Abu Huraira:

Two fasts and two kinds of sale are forbidden: fasting on the day of `Id ul Fitr and `Id-ul-Adha and the kinds of sale called Mulamasa and Munabadha. (These two kinds of sale used to be practiced in the days of Pre-Islamic period of ignorance; Mulamasa means when you touch something displayed for sale you have to buy it; Munabadha means when the seller throws something to you, you have to buy it.)

حَدَّثَنَا إِبْرَاهِيمُ بْنُ مُوسَى، أَخْبَرَنَا هِشَامٌ، عَنِ ابْنِ جُرَيْجٍ، قَالَ أَخْبَرَنِي عَمْرُو بْنُ دِينَارٍ، عَنْ عَطَاءِ بْنِ مِينَا، قَالَ سَمِعْتُهُ يُحَدِّثُ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ يُنْهَى عَنْ صِيَامَيْنِ، وَبَيْعَتَيْنِ الْفِطْرِ، وَالنَّحْرِ،، وَالْمُلاَمَسَةِ، وَالْمُنَابَذَةِ،‏.‏

Islam has laid down Laws of Islam rulings governing worshipful acts and transactions. It prescribes rulings pertaining to fasting, prayer, and other acts of worship, and also prescribes legislations to preserve people’s wealth. It is incumbent on a Muslim to abide by the divine commands and avoid the prohibitions set by the Laws of Islam. In this hadeeth, Aboo Hurayrah (may Allah be pleased with him) stated that the Prophet ﷺ forbade fasting on two days: ‘Eid Al-Fitr, because fasting people celebrate the breaking (end) of their fast after the month of Ramadan, and the second is the Day of Nahr, the tenth of Thoo al-Hijjah, because it is the day when the pilgrims perform Hajj rituals and offer animal sacrifices. Allah, Exalted is He, has bestowed His hospitality (i.e., prescribing the refrainment from fasting) on His servants in these two days, and therefore whoever fasts on those days would be rejecting His hospitality. Likewise, the Prophet ﷺ forbade two sales: Mulaamasah, which is an Arabic word derived from the root ‘La-ma-sa’, meaning touching. It refers to a way of selling practiced before Islam, and it means that when a buyer touches something displayed for sale, he has to buy it at the price decided by the seller. The second forbidden sale is: Munaabadhah, which is an Arabic word derived from the root ‘Na-ba-dha’, meaning renunciation. It also refers to a way of selling practiced before Islam, and it means that when a buyer throws something to the seller, the buyer has to buy it at the price decided by the seller. Both sales were conducted by people during the pre-Islamic era, and Islam forbade them, because they involve fraud and deception of the contracting parties (or one of them). The hadeeth also highlights the utility of the Laws of Islam to keep away from causes of discord and dissension among Muslims, forbidding certain transactions that were commonly practiced by people in the pre-Islamic era of ignorance. .
