Some Muslim thinkers such as Iqbal Lahoori and later, Dr. Shari'ati, assumed that the meaning of the end of Prophethood is the end of divine leadership and the rise of the rational guidance. They further assumed that man's intellect had reached a status where he no longer needed divine guidance. His intellect has been replaced with revelation.[i][i]
The above interpretation of the seal of Prophethood is very misleading and results in nothing other than secularism.
The actual meaning of the seal of Prophethood is that the package of the religion of God was completed and perfected and God did not need to send any more revelations to man. The perfected religion, i.e. Islam, is sufficient for all the needs of man forever. Man will not face any problems relating to his wellbeing for which the answer is not found in the teachings of Islam.
