This amount of time is certainly not enough and impossible to complete the great role of guardianship and carry this tremendous burden on the shoulders of only one Wasi. Perhaps if Ali lived for a hundred years after the Prophet’s death for example, his age may have been enough to accomplish the job.

But thirty years is certainly not enough, so therefore, we must anticipate the appearance of other Awsiyaa after him to continue his mission and complete his role which his lifespan did not permit him to complete. In addition, there were many battles, hostilities, and wars which occupied most of Ali’s time and did not give him enough opportunity to complete the role of Wasaya over the message with all its universality.

Thus, it is logical for us to deduce the essentiality of the presence of Awsiyaa (guardians) after him to complete the unfinished business due to the tough circumstances and instability that was present at the time of Ali ibn Abi Taleb (AS). This is logical based on the historical events which have already taken place posed as obstacles to the first Wasi. We must also take into consideration the nature of the nation which the Final Revelation descended to.

This ignorant and backward society was illiterate and very hard to deal with. The message came to transform this nation from its Stone Age which controlled its life and way of thinking, to a nation that would absorb this huge and rich message and transform it in such a way to adapt to this message. In order for this process of transformation and adaptation to happen in such a nation with a tough nature and attributes, it will certainly need a much longer time and greater effort.

Thus, the lifetime and efforts of one Wasi, or two, or four will not be sufficient. For example, suppose that you hired a clever cook and requested him to bake a very enormous cake that has no like in history. This cake should be beautified and decorated in such a way that is unique in magnificence and taste. So you provided him the raw materials he will need, but instead of giving him flour, you gave him the wheat spikes which he has to manually extract, peel, and grind from scratch.

Instead of giving him eggs, you gave him small chickens which he has to raise and wait until they lay their eggs. Instead of giving him chocolate powder, you gave him the cocoa beans and left it up to him to plant it, harvest, break, grind it and take the end product.
