1 Wahee-e-Matlu:

It means the revelation which God has transmitted in His own words and speech, for example the Quran. It is essential that such revealed words should be recited in the same accent, diction and pronunciation as they were revealed. Thus even after 1400 years Quran has remained unchanged.

2 Wahee-e-Ghair Matlu:

It is the revelation which Allah projected in the heart of the Holy Prophet. These are not the words of the Almighty, but the Holy Prophet (PBUH) transmitted these revealed edicts to the people in his own words.
