The Sharee'ah aims to eliminate frustration. In every condition the Sharee'ah endeavours that man is at peace. Whether it be in sorrow or in happiness, it is the Sharee'ah's aim that man is at peace, not of frustration. The Sharee'ah teaches the way of lightening grief and sorrow. Its teaching regarding peace augment the factors of peace so that these are not destroyed. If the correct principles are adopted, no one will become frustrated. There is no frustration in the Deen whether it be in the realm of Ahkaam-e-Zaahirah (the external laws) or Ahkaam-e-Baatinah (the internal laws, pertaining to the soul).
