Instead of giving him milk...
Instead of giving him milk, you gave him small calves to look after and then milk it afterwards. And so on and so forth, instead of handing him the simple raw materials that will suit the great task at hand, you provided him the complicated and difficult raw materials that are hard to use or deal with. In such case, do you think that the cook can accomplish this great task all by himself in such a short period of time, especially considering its complicatedness and the challenging raw materials?
Or don’t you think that he will logically need many helpers and assistants, as well as days and months to accomplish this great task with such complicated raw materials? The nature of the Arab nation during that time necessitates that there should be several Awsiyaa after the first Wasi to complete the mission in order for the newborn message to continue its growth and development until it reaps its fruits and accomplishes its goals.
One who studies the psychological, sentimental, and intellectual components of this nation during that time will immediately realize the difficult and complicated raw material that was present at that time. He will realize the need for continuous guardianship after the first Wasi for a long period of time afterwards.
The multitude and diversity of enemies against the Islamic message continued on afterwards especially after the Islamic conquests and that certainly indicates the need for many Awsiyaa. After all, if the hostility against Islam ended with the death of the first Wasi, then there would not be the need for multiplicity of Awsiyaa after him.
However, the continued increase of these enemies and the presence of means for destruction, whether from inside the Arab nation or from other nations, posed a direct threat to the existence of Islam. This calls for the necessity of having more than one Wasi who would stand up and protect the message. This is indeed a logical proof to the presence of those who would carry out this role, so long as the Message has yet to grow and establish itself, at least in the nation in which it descended.
The conquest of many countries in the East, West, North and South by Muslims, the embrace of inhabitants of these countries into this new religion, and the entrance of most of these different countries into Islam led to important influences and new circumstances which affect the atmosphere and climate in which the Final Message developed during the period of its growth, development, and establishment.
