The pinnacle at which argumentation and divine understanding naturally culminate is to what the term ‘Seal of Prophethood’ (khatm-e-nubuwwat) refers. To raise criticisms after this, like the irreligious, is the work of those who are bereft of faith. All things are characterised by clear facts and one’s ability to comprehend them depends on completeness of understanding and enlightenment of vision.
With the advent of the Messenger of Allah, peace and blessings of Allah be upon him, faith and divine knowledge reached perfection, and other nations were granted light as well. No other religion was bestowed such a manifestly clear and brilliant shariah. If anyone had received such a law, would it have not wielded the power to influence the Arabs even slightly? The sun which rose from among the Arabs illuminated every people and shined its light on every village.
It is the sole pride of the Noble Quran alone that it has the ability to reign supreme over all the other world religions in the matter of God’s Unity and prophethood. It is a matter of pride for the Muslims that they have been granted such a book. Those who attack the teachings of Islam and level allegations against its teaching and guidance do so only out of their own benighted nature and lack of faith.
