Introduction
As we all know, it is the duty of every human being to research about true religion and then follow it. As Muslims, we have recognized Islam as the true path among all religions. Thus, we need to study various Islamic denominations and schools, each of which considers itself the true Islam, and adhere to the one which is the best according to the verses of the Holy Qur’an and the Prophetic narrations. One of the most important differences between Islamic denominations is the issue of the Prophet's succession.
