This is oven fresh from Mufti Rafi Usmani Sahab (DB). People limit Islam to Madarsa, Tabligh and Jihad. This is a gross error. Every aspect of our life is supposed to be governed by Islam. So much so that worldly disciplines like engineering, medicine and management too have a high priority in Islam - the are Social Duties (Fard-e-Kifayah). Islam is all inclusive frame work for life.
