The people of Madyan didn't accept Lord as the Only Deity and were involved in corruption in weight and measures. Thus they became the mischief-makers throughout the countries. They were also involved in robberies. Thus they obstructed mankind from the Straightpath, and so life in that country became very difficult for mankind. Thus Lord Allah deputed Shuhaib as a Prophet for reforming them and to unload their life burden.
