Is it true that the Messenger used to read and write, and that (the illiterate) is a reference to Umm al-Qura?

Question:
Honorable Shaykh, may Allah grant you success, a message has spread via mobile phones stating that the Messenger of Allah (peace and blessings be upon him) was not illiterate, but rather that he read and wrote, and that the reason he was called "the illiterate" is that he was from Umm al-Qura. Is this correct?

Answer:
The one who says this is a liar. Allah named the Prophet (peace and blessings be upon him) "the illiterate." Allah named him "the illiterate" so he was illiterate, neither reading nor writing. Therefore, whenever he needed something written, he would call for someone to write it for him (peace and blessings be upon him).
