What is the ruling on a man working as a fashion model for men's clothing in Italy, and what is the ruling on the money earned from this work?

It is permissible to work in fashion design and receive payment for it, provided the work is free from Sharia (definition) prohibitions. These include the unveiling of 'awrah (which for a man is the area between the navel and the knee), or if the designs involve imitation of disbelievers, as the Prophet, peace and blessings be upon him, said: "Whoever imitates a people is one of them." A Muslim in lands of disbelief should be cautious about his religion and consult scholars before undertaking such work.
