In Light of Quraan and Hadith

ALLAH (the Creator) began the system of guidance to humanity through His venerable Messengers and Prophethood, beginning with Hazrat ADAM (Peace be upon him) and finally ending with the last prophet of all time, Hazrat Muhammed (Sallallahu Alayhi Wassalam). Afterward, no new prophet is to be. 

All types of nubuwwat is closed eg, ZILLI, Burozi, Tashreri, or non-Tashrehi. Similarly, the revelation through prophethood is also closed after Hazrat Muhammed (Sallallahu Alayhi Wassalam), and likewise, any revelation through which the reformation of ISLAM is claimed. The Quran is the last complete and most perfect book of revelation, which is unalterable. The contents of this book are safeguarded by ALLAH himself. 

It is the unanimous decision by evidence of countless Quranic revelations and hundreds of Ahadith of the Prophet Muhammed (Sallallahu Alayhi Wassalam), the consensus of sahaba (ALLAH be pleased with them), and the Ulama and intellectual scholars that MUHAMMED (Sallallahu Alayhi Wassalam) is the last prophet and messenger of ALLAH, this Shariat is the last Shariat, and this ummah is the last Ummah. 

The above-mentioned statements and their beliefs and admission by heart are the essential elements of faith in ISLAAM. In ISLAAM this faith is called the faith of Khatme Nubuwwat. It is the consensus of the Muslim Ummah that after MUHAMMED (Sallallahu Alayhi Wassalam), any person who claims to be a prophet and claims to be a messenger is a KAZZAB (liar) and Dajjal (deceiver), is an imposter and false. He has no relation with ISLAAM, similarly, a believer of such a liar also becomes Kafir (non-believer). 

Here are some references from Quraan and Ahadith related to the prophet MUHAMMAD (Sallallahu Alayhi Wassalam) being the KHATEM UN NABIYEEN (finality of prophethood).

References From Quraan

“MUHAMMAD is not the father of any man among you, but is the messenger of ALLAH and is the seal on the prophets, and ALLAH is aware of all things.” 
(Para 21 Surah Al Ahzab Ayah 40)

“This day, I have perfected your faith and completed all my favors upon you; and have chosen ISLAAM for you as your religion” 
(Para 6 Surah Al-Maida 5)

References From Ahadeeth

Hazrat Abu Hurairah (ALLAH be pleased with him) narrated that ALLAH’s messenger (Sallallahu Alayhi Wassalam) said;
“Certainly my example and the example of prophets earlier than me is like the example of a palace most elegantly and most beautifully constructed by a person except (that he left in it ) a (space) for a brick in one of its corner and that made the people (who were) going around it wonder (at its beauty) and exclaim ( in perplexion) why is there no brick inlaid here? the Prophet (Sallallahu Alayhi Wassalam); I am that (corners last) brick and I am the last of the prophets”. 
(Shahih al Bukhari,book Al Munaqib,Chapter 3 Khatam un nabiyeen p501 vol 1)

It is narrated by Hazrat Tahuban (ALLAH be pleased with him) that our prophet (Sallallahu Alayhi Wassalam) said;
“In my UMMAH there shall arise thirty liars, each of them will pretend that he is a prophet, but I am the last of the prophets; there is no prophet after me”. 
(Abu Dawood Vol . 2 p.228,Tirmizi Vol 2 p.45 )

Hazrat Ibne Masood (ALLAH be pleased with him ) has narrated that the Prophet (Sallallahu Alayhi Wassalam) said;
“The doomsday would not happen until 30 Kazzabbs (liars) have arisen all who claim to be prophets Although I am last of the prophets and there is none after me” 
(Muslim Sharif Tirimizi Sharif & Abu Dawood Sharif)

There are so many proofs for MUHAMMAD (Sallallahu Alayhi Wassalam), the messenger of ALLAH to establish the last prophet that it is impossible to write them here. During the last 1400 years, thousands of books have been published wherein such positive proofs are cited that no sensible person can dare refute or reject them. 

Prophet MUHAMMAD (Sallallahu Alayhi Wassalam) said
“I am the last prophet there is no prophet after me”

and instantly warned his UMMAH that there would be liars claiming prophethood.

The Muslim UMMAH not only strongly refuted the pretensions of such liars, but sacrificed their lives for the protection and honor of KHATAM UN NABIYEEN. Here are some events of the past. 

ASWAD ANSI 

Aswad Ansi was a resident of Yemen. He claimed prophethood during the illustrious lifetime of MUHAMMAD (Sallallahu Alayhi Wassalam). He marched on to conquer NAJRAN in the first instance, then turned towards SANA. Then all of Yemen came into his suzerainty. It became known that most of Yemen had become infidels and accepted the faith of Aswad’s prophethood. Prophet MUHAMMAD (Sallallahu Alayhi Wassalam) dispatched a memorandum to the Yeminites, who rejected the faith of Aswad’s prophethood to execute Aswad. 

Fayruz al-Daylami, one of the most prominent sahaba, defeated and executed Aswad in his historical conquest. Prophet MUHAMMAD (Sallallahu Alayhi Wassalam) had received the news of Aswad’s execution through revelation. The Yemenis had sent a messenger to prophet MUHAMMED (Sallallahu Alayhi Wassalam) with the news of Aswad’s execution in compliance with orders, but the prophet MUHAMMAD (Sallallahu Alayhi Wassalam) passed away before the messenger could reach Madinah. 

MUSAYLIMA AL-KADHĀB

Musaylimah was a resident of Yamamah. He claimed prophethood before the demise of the prophet MUHAMMED (Sallallahu Alayhi Wassalam). People in large numbers became infidels and supporters of Musaylimah. The battle of Yamamah took place during the caliphate of Hazrat Abu Bakar Siddique (May ALLAH be pleased with him). In this battle, Musaylimah Kazzab was condemned to hell. His 20,000 followers died as well. In this battle, just over 1,200 sahabah, including Huffaz and those who had participated in the battle of Badr, were among the martyrs, and in this way, the revolt came to its inevitable end. 

MIRZA GHULAM AHMED QADIANI

A resident of Qadiyan, which is a town in Punjab (presently in the Indian part of Punjab), Mirza Ghulam Ahmed claimed prophethood in 1901 during the British rule in India. He fell victim to cholera, an epidemic disease, and died ignominiously in Lahore Pakistan. His infidel beliefs had a short list. Since then all the ULAMA have excluded him and his followers from the fold of ISLAAM. The deceased Mirza Qadiani’s first successor is Khalifa Hakim Noor Ud Din, the second is Mirza Mahmood, the third is Mirza Nasir, and the fourth is Mirza Tahir residing in London in political asylum. All Qadianis are recognized and treated by the MUSLIM UMMAH as infidels. In Pakistan, all Qadianis had been officially declared as NON-MUSLIMS in 1974.

Subsequently, in 1984 an anti-Qadiani ORDINANCE was enforced as a result of which Mirza Tahir fled from Pakistan and sought refuge in England and resides in London. Qadianis regard themselves as a group of Muslims. They engage themselves in activities with the profile of ISLAAM by which some ignorant and simple Muslims become victims of their deception. All Muslims need to be aware of their machinations in religious or other social engagements.
