Compiled by Imam Muhammad al-Bukhari
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،.
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.)
