The Holy Prophet Muhammad (Sallallahu Alaihi Wassallam) said: “Never has anyone eaten a better thing than what he has eaten of the labour of his own hands.” He said: “Verily the purest of what you eat is of your own earnings.”
This important pronouncement of Sayyiduna Rasoolullah (Sallallahu Alaihi Wassallam) made in an age quite remote from ours has brought a revolution in the industrial world. What order can be greater than his magnificent utterance that the purest of what we earn is of our own earnings.
This led the Emperors and Saints to take up works and live upon their wages. This injunction led the Muslims to invent machineries of works and various ways of workmanship and manufacturing articles and commodities of common and extraordinary use.
According to the instruction of Sayyiduna Rasoolullah (Sallallahu Alaihi Wassallam), we should ourselves manufacture these articles and supply our needs therewith.
