Second : Advise and urge the people to follow and obey the orders of Allah (SWT) and to carry out the instructions and teachings of the divine message. Third : Obey and carry out the orders of Allah (SWT) with absolute care in the individual and specific roles that are assigned to each one of them, in addition to their general responsibilities, without any addition or subtraction.
Fourth : Set a good example and become roles models for the people in obeying the rules of Allah (SWT) and not disobeying Him under any circumstances (such that the people imitate and follow their example). Fifth : Rule justly between the people according to what Allah (SWT) revealed and His orders, and thereby set the example to the people how to judge between others in that same manner.
Sixth : Specify the guidelines and foundations which the human society will be built on including its relation with its surroundings and its interior (exactly as Allah commanded), and to execute it out to the best of their abilities. Seventh: Teach the people the wisdom, the lessons, and the laws of the religion as Allah (SWT) commanded, with what Allah (SWT) instructed, and with what they received from Him.
After quickly and briefly displaying the roles and responsibilities of the Prophets, Messengers, Awsiya', and Imams (AS) on Earth, what do you think are the things that they should be cleansed and purified from in order for them to perform their jobs in the best way possible?
And if their responsibilities is of highest degree of importance and vitality…and certainly it is of great and critical importance since it deals with the fate of a person in his Hereafter and his life of this world…then there is nothing more important and vital than that! Therefore, it is incumbent and necessary that their success in their responsibilities and roles is guaranteed to a percentage that might very well reach 100%.
And for that to happen, they must be cleansed and purified from anything that might cause their failure or hinder their success. Furthermore, this purification must reach almost or equal to 100%. Now, if the responsibilities and work that they will carry out is for the Great Creator, and is by the order and assignment from Him, it becomes logically necessary that He becomes the Mutahir in a direct way, due to the critical importance of the responsibilities and because it is for Him and from Him.
