Those who fulfill God’s covenant (responsible for the order in the universe, and able to establish the peace, order and harmony in human life) and do not break the pledge (that they shall worship none save God, and fulfill all the moral, spiritual, and social obligations resulting from believing in and worshipping only One God)
Those people of insight who: Are true to their bond with Allah (their allegiance to the Divine System). Keep their pledge with Allah and with human beings
Those (who reach the reality) fulfill the covenant of Allah (live according to the requirements of the knowledge of the reality manifested in their being by Allah) and they do not break their contracts (their natural disposition).
Sayyed Abbas Sadr-Ameli
