30. Can a caliph put an end to the
turmoil in the Muslim world today?

Problems are a part of nature and no one is capable of eliminating them, not even a caliph. Even the period described as the Golden Era of Islam (of the Prophet, the Companions of the Prophet and the Followers of the Companions), was not devoid of problems.

It must, however, be noted that the world is created in such a manner that it is not possible that a difficulty be present without the presence of ease or opportunities. Ease is always present along with a difficulty. The Prophet said that a believer relies on patience. This means that in difficult situations, we should keep patience. The Quran says:

With every hardship, there is ease (Quran 94:5-6)
