Key Verses

1. 2:198Al-Baqarah
   لَيۡسَ 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 no sin for you that ye seek the bounty of your Lord (by trading). But, when ye press on in the multitude from 'Arafat, remember Allah by the sacred monument. Remember Him as He hath guided you, although before ye were of those astray.
   In context

   There is no sin in seeking lawful provision by trading or other ways during the Hajj. When you leave Arafat after having spent the day there on the 9th of Dhū Al-Ḥijjah, and when you head towards Muzdalifah on the night before the 10th of Dhū Al-Ḥijjah, remember Allah by glorifying and praising Him and by praying to Him at the sacred place in Muzdalifah.
