Sealing of Prophet Hood is established according to the most authentic sources
Allah SWT says in the Holy Quran, " Muhammad (صلی اللہ علیہ وآلہ وسلم ) is not the father of any man among you, but he is the messenger of Allah and the seal of all Prophets: and Allah is ever Aware of all things." Surah Ahzab Verse no-40
This verse of the Quran Al-Kareem establishes explicitly that The Pride of the Creatures, the raison d’être of the universe, Our Master Hadhrat Muhammad Mustafa (صلی اللہ علیہ وآلہ وسلم ) is the Last and Final prophet. After Him, no Prophet of any kind will come. The series of Prophethood has been terminated on Him. Arrival of any Prophet after Him is inconceivable and impossible. There is no place left in the Palace of Prophethood that any prophet after Him should fill. Prophethood has been concluded with Him.
