EDUCATION:
In those days literacy was not common in Mecca and only a few people knew how to read and write. Muhammad (Peace Be Upon Him) was raised illiterate. He was unable to read or write, and remained like that till his death.
It pleased the Will of God, All-wise and All-knowing, that His Prophet (Peace Be Upon Him) should remain a stranger to the arts of reading and writing. His contemporaries could thus never accuse him of himself editing the divine revelations. This, too, has been subverted by the Quran to settle the matter as evidenced by the following verse:
"And thou (O Muhammad) was not a reader of any Scripture before it, nor didst thou write it with thy right hand, for then might those have doubted, who follow falsehood." (29: 48)
That is why the Quran calls him an 'unlettered prophet' (Peace Be Upon Him).
