KHATAM-E-NABUWAT

O people ! Muhammad has no sons among ye men, but verily, He is the Apostle of God and the Last in the line of Prophets (Khatam-un-Nabiyeen). And God is Aware of everything."
 (Surah Al Ahzab 33.40)

"There will be thirty liars in my Ummah, each of them claiming to be a Prophet,
but I am the Khatam-un-Nabiyeen, there is no Prophet after me."
(Sunan Abu Daud, Kitab al-Fitan)

Holy Prophet SAAW used the word Khatam-un-Nabiyeen for Himself and then qualified the meaning of this word by adding that "there is no Prophet after me."  Most certainly He knew that there will be some sick minded people in his ummah who will make all sorts of far flung distorted meanings.

He was conferred with the unique honor of:

"The Seal of the Prophets."

So none to appear after him. And none has! 

Says the Qur'an:

"Obey Allah and obey the Prophet."
