Is it permissible to work in a BROKERAGE HOUSE in an Islamic country ?

Praise be to Allah, the Lord of the Worlds; and blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.
Brokerage which is a mediation between a seller and a purchaser to arrange the details of a deal or to guide to suitable goods is permitted in Muslim countries and elsewhere. But one should not help anyone in selling or purchasing what is forbidden. Muslim Jurisprudents discuss this subject in the chapter of wages and its ruling is given in that chapter Allah knows best.
