Surah Al-Baqara Verse 198 - English Translation by Muhammad Sarwar
Surah Al-Baqaraلَيۡسَ عَلَيۡكُمۡ جُنَاحٌ أَن تَبۡتَغُواْ فَضۡلٗا مِّن رَّبِّكُمۡۚ فَإِذَآ أَفَضۡتُم مِّنۡ عَرَفَٰتٖ فَٱذۡكُرُواْ ٱللَّهَ عِندَ ٱلۡمَشۡعَرِ ٱلۡحَرَامِۖ وَٱذۡكُرُوهُ كَمَا هَدَىٰكُمۡ وَإِن كُنتُم مِّن قَبۡلِهِۦ لَمِنَ ٱلضَّآلِّينَ
It is not a sin if you try to make a profit out of the bounty of your Lord (by trading during hajj). When you leave Arafah, commemorate the name of your Lord in Mash'ar, the sacred reminder of God. Commemorate His name as He has given you guidance while prior to that you had been in error
