Sales and Trade
Chapter: Whoever bought foodstuff without measuring or weighing should not sell before bringing into house
Narrated Ibn `Umar:
I saw the people buy foodstuff randomly (i.e. blindly without measuring it) in the lifetime of Allah's Apostle and they were punished (by beating), if they tried to sell it before carrying it to their own houses.
