Seal of the Prophets
Muhammad is not the father of any of your men, but He is the Messenger of God and the Seal of the Prophets.- Qur'an 33:40

Disclaimer (on Interpretation): Beseech God, and let your prayerful attitude and a clean heart guide you to see the meanings in God's words.
The word "Seal" (kha'tam in Arabic), in the verse above, has been interpreted over the centuries to mean the: "Last", "Final", "Seal" (as in a stamp sealing closed a document), "Seal" (as in seal of authority, officiating a document), and a few other meanings along similar lines of interpretation. Baha'is don't object to these possible meanings, and readily believe in the more common interpretation of : (Seal meaning Last), as Muhammad (PBUH) is repeatedly referred to in the Baha'i Writings. This may at first appear contrary to believing that there is a new religion, but the visitor is invited to read further.

Followers of all past religions have believed, based on certain verses in their holy books, that their religion would not be followed by any other.

Verses such as this have prevented the Jews from accepting newer revelations:
"Go thy way, Daniel, for the words are closed up and sealed till the time of the end."- Daniel 12:9
Another verse in the Old Testament says that the law of the Sabbath shall not be broken.

For our Christian brothers and sisters, it was verses such as these below, which lead them to believe that there would not be any revelation after that of Christ:
"Jesus saith unto him, I am the way, the truth and the life; no man cometh unto the Father, but by me."- John 14:6

"Heaven and earth shall pass away: but my words shall not pass away."- Luke 21:33
"In the past God spoke to our forefathers through the prophets at many times and in various ways, but in these last days he has spoken to us by his Son, whom he appointed heir of all things, and through whom he made the universe. "- Hebrews 1:1
These and many other verses that talk about, how only through Jesus (PBUH) we can know the Father, and how His words will never be replaced, were the reason that Christians would not accept any Messenger after Christ.

Going back to the meaning of the "Seal of the Prophets", this verse, and other verses about the
completion of religion in Islam, have been interpreted by the majority of Muslims as indication of the finality, not only of Prophethood, but of all revelation. Other opinions and interpretations, including some by Muslim scholars, have argued that since there are many other verses in the Qur'an which explain the endless nature of the Words of God, in addition to other verses and Hadiths (traditions and sayings of the Prophet), which talk about the return of Jesus and the coming of the Mahdi, these opinions, have argued that there may be other interpretations for these verses. Some of these interpretations are mentioned here:
Oneness of the Prophets
Difference in Station between a Messenger (Rasool), and Prophet (Nabi)
Renewal of Creation necessitates Continuance of Revelation
Prophethood is not Inherited in Islam as was the case in Judaism

Dear Sir,
I humbly invite you to embrace Islam and testify that there is no God worthy of worship but Allah and that Muhammad is His final Prophet and Messenger.I
t is impossible to believe all religions are true, because they contradict each other. This is what Bahaullah failed to realize.
Islam is the religion of all of the Prophets from Abraham to Moses to Jesus to Muhammad (peace be upon them all).
The Bahai faith cannot be true because you claim that Allah can become manifest in His creation. You also claim that the Bab is the Mahdi and Bahaullah is Jesus, but this cannot be for the Mahdi will be a pure-blooded Arab and Jesus was a pure-blooded Israelite born from a virgin.
Both Bab and Bahaullah were Persians and Bahaullah was not born from a virgin.
Furthermore, they did not fulfill any of the prophecies that the Mahdi and Messiah will fulfill.

Bahaullah wrote:"Were any of the all-embracing Manifestations of God to declare: "I am God", He, verily, speaketh the truth, and no doubt attacheth thereto. For it hath been repeatedly demonstrated that through their Revelation, their attributes and names, the Revelation of God, His names and His attributes, are made manifest in the world..."This is blasphemy and shirk.Surah al-Ikhlas, the 112th Chapter of the Qur'an, totally refutes this"Say! He is God, the One!The Eternally Besought of all!He does not beget, nor is He begotten.And there is nothing comparable to Him."You also claim the both Bab and Bahaullah were new Messengers who received revelation from Allah and that you have new Holy Books. This cannot be, for Muhammad ibn Abdullah (saw) is the Seal of the Prophets. Not only this, you believe that the Prophet Jesus (as) died physically on the cross while the Qur'an says he was neither crucified nor killed.As for the finality of the Prophet Muhammad (saw), here is the evidence:The word khatam/khatim means a seal of, the last part of, a completion of.
So when Allah says in the Qur'an says "khatam an-nabiyyin" Seal of the Prophets, that literally and explicitly means the seal, the last part, the absolute completion of the Prophets.There are numerous, numerous ahadeeth where the Prophet Muhammad (saw) explicitly states that he is the last Prophet.I am Muhammad, I am Ahmad, I am the al-Mahi (the Effacer) in that through me infidelity shall be erased; I am the al-Hashir (Assembler) in that people shall be assembled after me. And I am al-Aqib (the Last)[Muwatta of Imam Malik]The Prophet Muhammad (saw) said in his Farewell Sermon:"O People, NO PROPHET OR APOSTLE WILL COME AFTER ME AND NO NEW FAITH WILL BE BORN. Reason well, therefore, O People, and understand words which I convey to you. I leave behind me two things, the QURAN and my example, the SUNNAH and if you follow these you will never go astray."Sincerely,Abdullah
