Islam is the way that leads to the Lord, Allah. Like any other way, the soul of Islam, Sufism, requires the seeker of Allah to pass different stages to become One. The very first stage is sharia then the intermediary stages are tariqa, reality (haqiqa) and gnosis (marifa) whereas the last one is Faqr (Oneness).
Piety is infact aim of life and provision of the hereafter. Piety is base of perfect faith and heritage of Saints. Piety is Allah’s favour upon umma. Piety is a will of Allah. It is an elevated spiritual station. In fact, believer remains imperfect without piety as it a purification of soul, medium to gain blessings of Divine vision and key to His ultimate closeness and gnosis. Its literal meaning is ‘shield’, thus it saves one from dangers and harms. Whereas in sharia, piety is to avoid oneself from every act and thought which brings torment of Allah. Moreover, piety means to follow that path which blesses one with happiness of Allah.
