Dear brothers and sisters know that it is incumbent upon Muslims to believe that Prophethood has ended with the advent of Sayyidna Muhammad al-Mustafa Habib Allah (may the peace and blessing of Allah be upon him). This belief in the finality of Prophethood has been an established belief of the Muslims since the time of the Prophet (Allah bless him and give him peace). Every time a false prophet has arisen, the Muslims knew he was false because belief in the finality of Prophethood has been established as part of the Muslim’s aqidah (tenets of faith).
A fitna in India arose in the latter part of the 19th Century in the guise of the Qadiani heretical cult who claimed prophethood for their leader Mirza Ghulam Ahmad Qadian (lanat Allah alay) despite all the evidence against such a claim. What I would like to present are some clear proofs from the ulama of the past, ulama that predate the Qadiani fitna so no one can accuse them of being biased. What you will see is that it is quite clear, without a shadow of a doubt that finality of Prophethood is something that is necessarily known as being part of the religion of Islam. Hence the rejection of this belief is Kufr and quite rightly the Qadianis have been declared as kafir by the leading ulama of this ummah then and now.
Imam al-Tahawi (d. 321 AH) in al-Aqidah al-Tahawiyya states
“Every claim to prophethood after him is falsehood and deceit.”
Ibn Kathir (d. 774 AH) in Tafsir al-Qur’an al-Azim states
“”Muhammad is not the father of any man among you, but the Messenger of Allahand the Last of Prophets. And Allah has knowledge of everything”
This Qur’anic verse is an unequivocally decisive primary text [nass] that there will be no prophet after him. And since there will be no prophet (nabi), it follows a fortiori that there will be no prophetic messenger (rasul). The Prophet (Allah bless him and give him peace) said:
(1) “Messengerhood and prophethood have ceased. There will be no messenger or prophet after me.” [related by Ahmad]
(2) “My likeness among the prophets is as a man who, having built a house put the finishing touches on it and made it seemly, yet left one place without a brick. When anyone entered it and saw this, he would exclaim, ‘How excellent it is, but for the place of this brick.' Now, I am the place of the brick: through me the line of prophets (Allah bless him and give him peace) has been brought to completion.” [Related by al-Bukhari]
(3) “I have been favoured above the prophets in six things: I have been endowed with consummate succinctness of speech, made triumphant through dread, war booty has been made lawful for me, the whole earth has been made a purified place of worship for me, I have been sent to all created beings, and the succession of prophets has been completed in me.” [related by Tirmidhi and ibn Majah]
Allah Most Blessed and Exalted has stated in His book, as has His Messenger (Allah bless him and give him peace) in hadiths of numerous channels of transmission (mutawatir) that there will be no prophet after him, so that whoever claims this rank thereafter is a lying [kadhab] pretender [dajjal], misled and misleading, even if he should stage miracles and exhibit all kinds of magic, talismans and spells.”
Here ends the quotation from Ibn Kathir’s Tafsir al-Qur’an al-Azim 3.493-494 (cf. Reliance of the Traveller W4.2).
Here are some ahadith from Sahih al-Bukhari:
Narrated Abu Huraira: The Prophet said, “The Children of Israel used to be ruled and guided by prophets: Whenever a prophet died, another would take over his place. There will be no prophet after me, but there will be Caliphs who will increase in number.” The people asked, “O Allah’s Apostle! What do you order us (to do)?” He said, “Obey the one who will be given the pledge of allegiance first. Fulfil their (i.e. the Caliphs) rights, for Allah will ask them about (any shortcoming) in ruling those Allah has put under their guardianship.” [al-Bukhari 4.661]
Narrated Sa’ad: Allah’s Apostle set out for Tabuk. appointing ‘Ali as his deputy (in Medina). ‘Ali said, “Do you want to leave me with the children and women?” The Prophet said, “Will you not be pleased that you will be to me like Aaron to Moses? But there will be no prophet after me.” [al-Bukhari 5.700]
Narrated Abu Huraira: Allah’s Apostle said, “The Hour will not be established (1) till two big groups fight each other whereupon there will be a great number of casualties on both sides and they will be following one and the same religious doctrine, (2) till about thirty dajjals (liars) appear, and each one of them will claim that he is Allah’s Apostle, (3) till the religious knowledge is taken away (by the death of Religious scholars) (4) earthquakes will increase in number (5) time will pass quickly, (6) afflictions will appear, (7) Al-Harj, (i.e., killing) will increase, (8) till wealth will be in abundance . . .” [al-Bukhari 9.237]
Narrated Isma’il: I asked Abi Aufa, “Did you see Ibrahim, the son of the Prophet?” He said, “Yes, but he died in his early childhood.Had there been a Prophet after Muhammad then his son would have lived, but there is no Prophet after him.”  [al-Bukhari 8.214]
Narrated Ayesha (RA): “Prophethood will NOT continue after me, except the harbingers of good news”. They asked “What are the harbingers of good news, O Apostle of Allah?.” He replied: “Virtuous and pious dreams a Muslim sees or are shown to him”. Musnad of Imam Ahmad ibn Hanbal
Now, the above is just a small portion of the vast amount of mutawatir evidence that proves conclusively that there are no prophets after the Prophet Muhammad (Allah bless him and give him peace), if you believe that there is a prophet after him then you are a kafir, period. There is absolutely and utterly no room for any doubt in this matter. In the face of such overwhelming evidence then why is it that the Qadianis persist in their misguided and misguiding belief?
Written in response to Qadiani propaganda on the newsgroup soc.religion.islam
 mutawatir def: related by whole groups of individuals from whole groups, in multiple contiguous channels of transmission leading back to the Prophet himself, such that the sheer number of separate channels at each stage of transmission is too many for it to be possible for all to have conspired to fabricate the hadith (which makes it obligatory to believe in and denial of which is kufr). [cf. Reliance of the Traveller o22.1(dII)]
 I have seen a hadith quoted by the Qadianis in which Umm al-Mu’minin Sayyida Aisha is reported to have said “O ye Muslims ! Do proclaim that the Holy Prophet, peace and blessings of Allah be upon him, was the Khataman Nabiyeen, but never say that there shall be no prophet after him” [Takmilah Majma ul Bihar & Durr i Manthur], this hadith is a fabrication and is rejected. Witness the lies they invent and attribute to Umm al-Mu’mineen!
