A:
It is not permissible for a town dweller to sell goods on behalf of a desert dweller and it is similarly impermissible to receive trade caravans before they arrive at the market with a view to buying their goods at a lower price and then re-selling them in the market at a higher price. (Part No. 13; Page No. 122) The Messenger of Allah (peace be upon him) said,
"Do not meet the caravans (on the way to buy their goods without letting them know the market price). Also, a town dweller should not sell goods on behalf of a desert dweller."
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
