Why another Nabi (Prophet) can not come?

الجواب حامدا و مصلیا

The arrangement started by the Almighty Allah of sending His messages by revelation through the chain of His Prophets for the purpose of up bringing and reforming of the mankind has reached its completion with the advent of Hadhrath Muhammad Sallallahu Alaihi wa Sallam. Therefore now, there remains no necessity of a new Prophet. After completion of a thing it is against the wisdom to ask for an enhancement. Nabi Sallallahu Alaihi wa Sallam has compared the chain of Prophethood to a beautiful perfect building and said that “I am the last brick of it.” Therefore instead of engaging in this type of illogical questions and waiting for a new Nabi, one should concentrate on following Muhammad Sallallahu Alaihi wa Sallam so as to succeed in Dunya and Akhira.

Allah knows best.
