The Unlettered Prophet.

[Abu Hafsat]

As-Salaam alaikum, 

In ayat 157 of Surat A'araf (7:157), the Holy Qur'an referred to the sobriquet of Prophet Muhammad, Sallallahu alaihi Wasallam, as the "Unlettered Prophet". He did not attend any school for formal education... to learn how to read and/or write. The Prophet's knowledge came only from Allah, not from reflection and consideration. 

At the time of the creation of the Prophet's light, Allah Ta'ala gave him the Universal Intellect, called the Total Intellect as well as the Pen and the Guarded Tablet. He endowed him with the whole of His eternal Wisdom, bacause our blessed Master, Sallallahu alaihi Wasallam, is the source of light, which Allah drew directly from His own Essence. Consequently, the Prophet's personality contains all of Allah's Truth, which enabled him to see and understand everything... Sallallahu alaihi Wasallam.
