Islam is a complete code of conduct, and some of the commands that Allah has imposed on those who believe in Islam.
Allah says in the Quran:
“قُوۡلُوۡۤا اٰمَنَّا بِاللّٰہِ وَ مَاۤ اُنۡزِلَ اِلَیۡنَا وَ مَاۤ اُنۡزِلَ اِلٰۤی اِبۡرٰھِمَ وَ اِسۡمٰعِیۡلَ وَ اِسۡحٰقَ وَ یَعۡقُوۡبَ وَ الۡاَسۡبَاطِ وَ مَاۤ اُوۡتِیَ مُوۡسٰی وَ عِیۡسٰی وَ مَاۤ اُوۡتِیَ النَّبِیُّوۡنَ مِنۡ رَّبِّہِمۡ ۚ لَا نُفَرِّقُ بَیۡنَ اَحَدٍ مِّنۡہُمۡ ۫ ۖ وَ نَحۡنُ لَہٗ مُسۡلِمُوۡنَ
“(O Muslims!) Say: ‘We believe in Allah and in that (Book) which has been revealed to us and (also) that which was revealed to Ibrahim (Abraham) and Isma‘il (Ishmael) and Ishaq (Isaac) and Ya‘qub (Jacob) and their children and those (Books) too which were given to Musa (Moses) and ‘Isa (Jesus) and (likewise) which were given to other Prophets by their Lord. We do not make distinction between any of them (in the matter of faith), and we have submitted ourselves to Him alone (the Only, the One God).’”
In this verse Allah has stated in clear words that in order to be a Muslim, it is necessary to believe in Allah, His books and all the Prophets whom Allah has chosen and does not accept an other invitation of a Prophet. Every Heavenly Book and Prophet gave the news of the coming Book and the Prophet, but since the last book of the Holy Qur’an and the Prophet (peace and blessings of Allah be upon him) is the seal of the Prophets, so neither the Qur’an nor The Prophet (peace and blessings of Allah be upon him) mentioned an up coming prophet who came after him.
The proof for the belief that Prophet Muhammad (PBUH) is the last prophet is in the Qur’anic verses 40 and Surah Ahzab:[33:40] Al-Aḥzāb-الْأَحْزَاب
“مَا کَانَ مُحَمَّدٌ اَبَاۤ اَحَدٍ مِّنۡ رِّجَالِکُمۡ وَ لٰکِنۡ رَّسُوۡلَ اللّٰہِ وَ خَاتَمَ النَّبِیّٖنَ ؕ وَ کَانَ اللّٰہُ بِکُلِّ شَیۡءٍ عَلِیۡمًا ﴿٪۴۰﴾
Muhammad (blessings and peace be upon him) is not the father of any of your men, but he is the Messenger of Allah and the Last of the Prophets (ending the chain of the Prophets). And Allah is the Perfect Knower of everything.
The Hadith of Sahih Bukhari No. 3532 “The Prophet (peace and blessings of Allah be upon him) said:
“My five names are Mohammed, Ahmad and Mahi (ie, the eraser) that Allah will remove the disbelief through me and I am Hashir, and I’m Aqib means the end of the Prophets. No new prophet will come into the world after me.”
In a hadith, the Prophet (peace and blessings of Allah be upon him) said:
“The Hour will not be established until the two parties fight with each other, there will be a heavy battle between the two, while the two will claim to be the same, and the Hour will not be established until thirty false prophets are born. Everyone will claim that he is the Prophet of Allah” (Al-Bukhari 3464).
Hence, after the Messenger of Allah (peace and blessings of Allaah be upon him), any person who claims to be a prophet will be the Antichrist, so it is an important part of the faith that we should accept the Messenger of Allah (peace and blessings of Allah be upon him) as last of the Prophets. The follower of any other false prophets are actually actually following dajjal who has nothing to do with Islam .
