I was a man who used to give (riding-beasts) on hire for this purpose (for travelling during the pilgrimage) and the people would tell (me): Your hajj is not valid. So I met Ibn Umar and told him: AbuAbdurRahman, I am a man who gives (riding-beast) on hire for this purpose (i.e. for hajj), and the people tell me: Your hajj is not valid. Ibn Umar replied: Do you not put on ihram (the pilgrim dress), call the talbiyah (labbayk), circumambulate the Ka'bah, return from Arafat and lapidate jamrahs? I said: Why not? Then he said: Your hajj is valid. a man came to the Prophet ﷺ and asked him the same question you have asked me. The Messenger of Allah ﷺ kept silence and did not answer him till this verse came down: "It is no sin for you that you seek the bounty of your Lord." The Messenger of Allah ﷺ sent for him and recited this verse to him and said: Your hajj is valid.  

فَإِنَّ لَكَ حَجًّا جَاءَ رَجُلٌ إِلَى النَّبِيِّ ﷺ فَسَأَلَهُ عَنْ مِثْلِ مَا سَأَلْتَنِي عَنْهُ فَسَكَتَ عَنْهُ رَسُولُ اللَّهِ ﷺ فَلَمْ يُجِبْهُ حَتَّى نَزَلَتْ هَذِهِ الآيَةُ { لَيْسَ عَلَيْكُمْ جُنَاحٌ أَنْ تَبْتَغُوا فَضْلاً مِنْ رَبِّكُمْ } فَأَرْسَلَ إِلَيْهِ رَسُولُ اللَّهِ ﷺ وَقَرَأَ عَلَيْهِ هَذِهِ الآيَةَ وَقَالَ لَكَ حَجٌّ  

The people used to trade, in the beginning, at Mina, Arafat, the market place of Dhul-Majaz, and during the season of hajj. But (later on) they became afraid of trading while they were putting on ihram. So Allah, glory be to Him, sent down this verse: "It is no sin for you that you seek the bounty of your Lord during the seasons of hajj." Ubayd ibn Umayr told me that he (Ibn Abbas) used to recite this verse in his codex.  

أَنَّ النَّاسَ فِي أَوَّلِ الْحَجِّ كَانُوا يَتَبَايَعُونَ بِمِنًى وَعَرَفَةَ وَسُوقِ ذِي الْمَجَازِ وَمَوَاسِمِ الْحَجِّ فَخَافُوا الْبَيْعَ وَهُمْ حُرُمٌ فَأَنْزَلَ اللَّهُ سُبْحَانَهُ { لَيْسَ عَلَيْكُمْ جُنَاحٌ أَنْ تَبْتَغُوا فَضْلاً مِنْ رَبِّكُمْ } فِي مَوَاسِمِ الْحَجِّ قَالَ فَحَدَّثَنِي عُبَيْدُ بْنُ عُمَيْرٍ أَنَّهُ كَانَ يَقْرَأُهَا فِي الْمُصْحَفِ  

In the beginning when Hajj was prescribed, people used to trade during Hajj. The narrator then narrated the rest of the tradition upto the words, ʿseason of Hajj’.  

أَنَّ النَّاسَ فِي أَوَّلِ مَا كَانَ الْحَجُّ كَانُوا يَبِيعُونَ فَذَكَرَ مَعْنَاهُ إِلَى قَوْلِهِ مَوَاسِمِ الْحَجِّ
