When this act of performing wudhu which does not seem to have any reason for its alteration have been altered by the conspirators then for sure major alteration must have taken place in the ahkam (rules) that belongs to law and order in order to benefit desires of different groups.
By focusing upon these points it becomes clear that the religion of Islam will be known as a perfect religion - which attends to the all needs of man - if it provides the society with the essential benefits which are not consign and endangered after the demise of the prophet. However this is only possible with the nomination of an individual who deserve the position of being a successor to the prophet.
This successor must possess the divine knowledge and have the ability to manifest the reality of deen in different dimensions and he must be unsinning (ma’sum) in order not to be under the influence of his nafs and shaitan so that there be no alteration in the deen. Furthermore he must play the role of the prophet in training individuals to arrive upon perfection and at the same time he should establish a government if the sociological conditions provides the grounds for it.
Then by applying the sociological ahkam of Islam in the society he should expand the realm of ’adl (justice) in the world. Hence the termination of the chain of nabuwah is only harmonious with the Divine hikmah when it is concurrent with the nomination of an Imam al ma’sum who have all the particularities that the prophet of Islam had except the nabuwah and risalah.
In this manner (three things are established), the necessity for an existence of an Imam and the requirement of the divine knowledge and sinlessness (’ismah). In addition to this the nomination of an Imam through God, the Supreme is also established as it He who knows to whom He should give this status to. In actuality it is God who has the right of wilayah (authority) over His creation and hence He can decide whom to give this position on a lower level.
It is necessary that we mention that the ahl Sunna jammah does not have these conditions and particularities for any of the khilafah and they do not even claim that God and the prophet nominate the caliphs or they (caliphs) possess any divine knowledge.
