Finality of Prophethood

This dude claimed that there is no where that Muhammad confessed by himself that he was the last prophet ...

Quran

Muhammad is not the father of any of your men, but (he is) the Messenger of Allah, and the Seal of the Prophets: and Allah has full knowledge of all things. 

(The Holy Quran, Al-Ahzab 33:40)

 Confession of the Prophet Muhammad

And We never sent a messenger save with the language of his folk, that he [Hazrat Muhammad(SAW)] might make (the message) clear for them. Then Allah sendeth whom He will astray, and guideth whom He will. He is the Mighty, the Wise.

(The Holy Quran, Ibrahim 14:4)

The following teachings of Prophet Muhammad(SAW) deal with the issue of Finality of Prophethood. As apparent from the references, these Ahadith are authentic and have been recorded by many scholars and reported by numerous companions of the Prophet(SAW).

My position in relation to the prophets who came before me can be explained by the following example: A man erected a building and adorned this edifice with great beauty, but he left an empty niche, in the corner where just one brick was missing. People looked around the building and marveled at its beauty, but wondered why a brick was missing from that niche? I am like unto that one missing brick and I am the last in the line of the Prophets.

(Bukhari, Muslim,Tirmidhi, Musnad Ahmad, Tirmizi, Babu Khatimin-Nabiyyin, Musnad Abu Dawud Tayalisi)

God has bestowed upon me six favors which the former Prophets did not enjoy:

I have been endowed with the gift of pithy and perfect speech.

I was granted victory owing to my awe.

The spoils of war were made lawful unto me.

The whole earth has been made the place of worship for me and it has become the means of purification for me also. In other words, in my religion, offering of prayers is not confined to certain specified places of worship. Prayers can be offered at any place over the earth. And in case water is not available, it is lawful for my people to perform ablutions with earth (Tayammum) and to cleanse themselves with the soil, if water for bathing is scarce.

I have been sent by Allah to carry His Divine message to the whole world.

And the line of prophets has come to its final end in me.

(Muslim, Tirmidhi, Ibn Majah)

I am Muhammad, I am Ahmad, I am the effacer and infidelity shall be erased through me; I am the assembler. People shall be assembled on Doomsday after my time. And I am the last in the sense that no prophet shall succeed me.

(Bukhari, Muslim, Tirmidhi, Muatta')

You (Hazrat Ali) are related to me as Aaron was related to Moses (pbuh). But no Apostle will come after me.

(Bukhari, Muslim  Musnad recorded a similar hadith ending in 'Behold there is no prophethood after me.')

If ever there arose a person from among my people who would hold communion with God, it would be none else but 'Umar bin Khattab.

(Bukhari , Muslim, Tirmidhi)

We are the last (ummah) but will precede all on the Day of Resurrection except that the Book was given to them before us.

(Bukhari, Muslim)

The tribe of Israel was guided by prophets. When a prophet passed away, another prophet succeeded him. But no prophet will come after me; only caliphs will succeed me.

(Bukhari)

I am the last in line of the prophets of God and my Masjid is the last Masjid.

(Muslim)

The chain of Messengers and Prophets has come to an end. There shall be no Messenger nor Prophet after me.

(Tirmidhi, Musnad Ahmad, Anas bin Malik)

There will arise thirty impostors in my Ummah and each one of them will pronounce to the world that he is a prophet, but I am the last in the line of the Prophets of God and no Prophet will come after me.

(Abu Dawood, Tirmizi)

Allah will send no Apostle after me, but only Mubashshirat (Good vision or pious vision).

(Musnad Ahmad, Abu Tufail, Nasa'i, Abu Dawud)

No Prophet will come after me and there will, therefore, be no other community of followers of any new Prophet.

(Baihaqi, Tabarani)

God Almighty hath sent unto the world no apostle who did not warn his people about the appearance of Dajjal (Anti-Christ, but Dajjal did not appear in their time). I am the last in the line of Prophets and you are the last community of believers. Without doubt, then, Dajjal shall appear from amongst you.

(Ibn Majah)

I am Muhammad, the unlettered prophet of Allah. I am Muhammad, the unlettered prophet of Allah. I am Muhammad, the unlettered prophet of Allah. There will be no prophet after me.

(Musnad Ahmad)

These are just a brief listing of the authentic teachings of Hazrat Muhammad(SAW) available on the issue of the Finality of Prophethood; should a true believer have any doubt about the Finality of Prophethood?

It is not fitting for a Believer, man or woman, when a matter has been decided by Allah and His Messenger to have any option about their decision: if any one disobeys Allah and His Messenger, he is indeed on a clearly wrong Path.

(The Holy Quran, Al-Ahzab 33:36)
