Earning halaal wealth in a halaal manner cannot be over emphasized. Hazrat Rasulullah (sallallahu ‘alaihi wasallam) said that Allah Ta‘ala had given the believers the very same command that He had given the Ambiyaa and Rasuls (‘alaihimus salaam) – the command of earning and consuming that which is halaal.
The reason for Allah Ta‘ala commanding the Ambiyaa, Rasuls (‘alaihimus salaam) and believers to earn and consume halaal is that earning haraam and consuming haraam will only lead to one’s peril and destruction. If one consumes haraam, then one will be motivated to carry out haraam actions and the noor of the heart will be totally lost. Similarly, one’s good deeds will lose acceptance.
