Shaikh Isma’il Haqqi (died 1137 A.H.) while elucidating this verse in his commentary Ruh-ul-Bayan, writes: “Asim reads the word Khatam with a vowel stress on the letter ta which means the instrument of stamping and sealing, just as ‘Printer’ is the machine which imprints. The connotation of the word is that the Holy Prophet (pbuh) was the last of all prophets and God has sealed the office of prophethood through his agency. In Persian the same meaning will be expressed by the term ‘Mohar Paighambran’. The seal of Prophets i.e., his (Mohammed’s) advent sealed the door of prophethood and the line pf prophets ended in him. Other reciters pronounce the word Khatim with the vowel point under the letter ta which means to say that Mohammed (pbuh) was the one who sealed the doors of prophethood. In Persian the same meaning will be expressed by the term ‘Mohar Konindai Paighambran,’ ‘Sealer of the prophets,’ so both ways the word Khatam bears one and the same meaning……..Henceforth the Ulema of the Ummah of Mohammed (pbuh) will inherit only spiritual eminence from him. The inheritance of Prophethood is extinct, for Mohammed (pbuh) has sealed the office of Prophethood for all time to come. The appearance of Hadrat Isa (pbuh) after Mohammed (pbuh) is not a contradiction of the finality of Mohammed’s prophethood. The term Khatam-un-Nabiyyin makes it clear that no one will be appointed a prophet after Mohammed (pbuh).
Hadrat Isa (pbuh) was appointed Prophet before Mohammed (pbuh) and Isa (pbuh) will appear as a follower of the Shari’ah of Mohammed (pbuh). He (Isa) (pbuh) will offer prayers with his face turned towards the Qiblah designated by Mohammed (pbuh). Hadrat Isa (pbuh) will be one among the faithful of Islam. He will neither receive any Divine revelation nor will issue new injunctions; he will act as a follower of Mohammed (pbuh). `Ahl-Sunnat wal Jam’at (the Sunni sect) believe that no prophet will come after our holy Prophet Mohammed (pbuh) because God has affirmed wa-lakin Rasul Allehe wa Khatam-un- Nabiyyin, and the Prophet has said: La Nabiya Ba`di (There will be no Prophet after me.) Henceforth anyone who says that a prophet will succeed Mohammed (pbuh) will become an apostate, because he has denied a basic article of faith. Similarly anyone who casts doubt about the finality of Mohammed’s prophethood, will also be declared an infidel, because the foregoing discussion has distinguished right from wrong. And any claim to prophethood after Mohammed (pbuh) is absolutely false.”
