Sahih al-Bukhari 2050
Sahih al-Bukhari · Book 34: Sales and Trade · What has come in the Statement of Allah تعالى: “Then when the (Jumu‘ah) Salat is ended, you may disperse through the land, and seek of the Bounty of Allah.... And Allah is the Best of Providers.” (V.62:10,11)
Narrated Ibn `Abbas:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ ، حَدَّثَنَا سُفْيَانُ ، عَنْ عَمْرٍو ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ كَانَتْ عُكَاظٌ وَمِجَنَّةُ وَذُو الْمَجَازِ أَسْوَاقًا فِي الْجَاهِلِيَّةِ، فَلَمَّا كَانَ الإِسْلاَمُ فَكَأَنَّهُمْ تَأَثَّمُوا فِيهِ فَنَزَلَتْ {لَيْسَ عَلَيْكُمْ جُنَاحٌ أَنْ تَبْتَغُوا فَضْلاً مِنْ رَبِّكُمْ } فِي مَوَاسِمِ الْحَجِّ ، قَرَأَهَا ابْنُ عَبَّاسٍ .
`Ukaz, Majanna and Dhul-Majaz were marketplaces in the Pre-Islamic period of ignorance. When Islam came, Muslims felt that marketing there might be a sin. So, the Divine Inspiration came: "There is no harm for you to seek the bounty of your Lord (in the seasons of Hajj)." (2.198) Ibn `Abbas recited the Verse in this way.
