حَدَّثَنَا عُثْمَانُ بْنُ الْهَيْثَمِ، أَخْبَرَنَا ابْنُ جُرَيْجٍ، قَالَ عَمْرُو بْنُ دِينَارٍ قَالَ ابْنُ عَبَّاسٍ ـ رضى الله عنهما ـ كَانَ ذُو الْمَجَازِ وَعُكَاظٌ مَتْجَرَ النَّاسِ فِي الْجَاهِلِيَّةِ، فَلَمَّا جَاءَ الإِسْلاَمُ كَأَنَّهُمْ كَرِهُوا ذَلِكَ حَتَّى نَزَلَتْ {لَيْسَ عَلَيْكُمْ جُنَاحٌ أَنْ تَبْتَغُوا فَضْلاً مِنْ رَبِّكُمْ} فِي مَوَاسِمِ الْحَجِّ.

Narrated Ibn ' `Abbas:Dhul-Majaz and `Ukaz were the markets of the people during the Pre-Islamic period of ignorance. When the people embraced Islam, they disliked to do bargaining there till the following Holy Verses were revealed:-- There is no harm for you If you seek of the bounty Of your Lord (during Hajj by trading, etc)
