ʿUkaz, 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 ʿAbbas recited the Verse in this way.  

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  

ʿUkaz, Mijanna and Dhul-Majaz were markets during the Pre-islamic Period. They (i.e. Muslims) considered it a sin to trade there during the Hajj time (i.e. season), so this Verse was revealed:-- "There is no harm for you if you seek of the Bounty of your Lord during the Hajj season." (2.198)  

كَانَتْ عُكَاظٌ وَمَجَنَّةُ وَذُو الْمَجَازِ أَسْوَاقًا فِي الْجَاهِلِيَّةِ فَتَأَثَّمُوا أَنْ يَتَّجِرُوا فِي الْمَوَاسِمِ فَنَزَلَتْ {لَيْسَ عَلَيْكُمْ جُنَاحٌ أَنْ تَبْتَغُوا فَضْلاً مِنْ رَبِّكُمْ} فِي مَوَاسِمِ الْحَجِّ  

[Machine] Al-Qa'nabi narrated that Sufyan ibn 'Uyaynah narrated from 'Amr ibn Dinar who narrated from Ibn 'Abbas who said: "Okaz, Majannah, and Dhu al-Majaz were marketplaces during the time of Jahiliyyah. When Islam came, they continued to gather there, but without engaging in sinful activities. So, Allah revealed the verse: 'There is no sin upon you if you seek the bounty of your Lord' in regards to the times of Hajj."  

ثنا الْقَعْنَبِيُّ ثنا سُفْيَانُ بْنُ عُيَيْنَةَ عَنْ عَمْرِو بْنِ دِينَارٍ عَنِ ابْنِ عَبَّاسٍ قَالَ كَانَتْ عُكَاظٌ وَمِجَنَّةُ وَذُو الْمَجَازِ أَسْوَاقٌ فِي الْجَاهِلِيَّةِ فَلَمَّا جَاءَ الْإِسْلَامُ تَأَثَّمُوا فَأَنْزَلَ اللهُ ﷻ {لَيْسَ عَلَيْكُمْ جُنَاحٌ أَنْ تَبْتَغُوا فَضْلًا مِنْ رَبِّكُمْ} فِي مَوَاسِمِ الْحَجِّ  

[Machine] There were markets in 'Ukaz, Majannah, and Dhul-Majaz during the pre-Islamic era. When Islam came, they were forbidden from engaging in trade there. Allah then revealed the verse: "There is no blame upon you" (Surah Al-Baqarah 198) to seek the bounty of your Lord during the seasons of Hajj.  

كَانَتْ عُكَاظٌ وَمَجَنَّةُ وَذُو الْمَجَازِ أَسْوَاقًا فِي الْجَاهِلِيَّةِ فَلَمَّا كَانَ الْإِسْلَامُ تَأَثَّمُوا مِنَ التِّجَارَةِ فِيهَا فَأَنْزَلَ اللهُ ﷻ {لَيْسَ عَلَيْكُمْ جُنَاحٌ} [البقرة 198] أَنْ تَبْتَغُوا فَضْلًا مِنْ رَبِّكُمْ فِي مَوَاسِمِ الْحَجِّ
