It was also linked to partial and limited factors such Lenin's health, during his trip and when he entered Russia and led the revolution For had he met with an incident while on his way, he would have been delayed and the revolution would have lost its ability for that swift move.

However, the unchangeable custom of Allah in every Divine operation of change proceeded, in its executive side, in accordance with the objective circumstances that created the appropriate climate and the general atmosphere for its success. Hence Islam came only after a great gap and long period which lasted for centuries after the messengers.

Although Allah, the Exalted, could have overcome all the obstacles and difficulties that were on the way of the Divine message and created the appropriate climate by way of miracles, He preferred not to use such a style, since the tests, trials and the afflictions that make the human being perfect required that this Divine task be natural and objective.

However, this did not prevent Allah, the Exalted, from interfering from time to time with some details that did not shape the appropriate climate but which were sometimes needed for the movement within such a climate, such as the support that Allah, the Exalted, bestows on his saints during some of their difficult moments, so as to protect the message So suddenly Numrud's fire becomes cool and a peace for Ibrahim.

When the traitor's hand which was bearing the sword to strike the Prophet's hand was suddenly paralysed and lost its ability to strike, also when suddenly the storm swept away the unbelievers and the polytheists' camps, when they were encircling Medina, on the Day of the Ditch (yawmu'l-Khandaq ), thus terrorizing them.

However, all of these events did not go beyond certain details and the provision of assistance during some decisive moments after the appropriate atmosphere had been already formed for the operation of change in a natural way and in accordance with the objective circumstances.

In this light we can examine al-Mahdi's position to find that the operation of change, for which he had been prepared, is linked, on the executive side, as is the case with any other operation of social change to certain objective circumstances that participate in securing the convenient climate under which it will occur. We must bear in mind that al-Mahdi has not been prepared for a limited social task nor for an operation of change limited to a particular part of the world or another.
