The Noble Prophet Muhammad, Sallallahu alaihi Wasallam,said:--
"TIME HAS NOW COME FULL CIRCLE AS IT WAS THE MOMENT ALLAH CREATED
THE HEAVENS AND EARTH." [Bukhari and others].
From this, we can understand that Prophethood is a circle, or a ring of connected points; each point representing a Prophet... and that point which GATHERS and SEALS both arcs of the circle represents MUHAMMAD, Sallallahu alaihi Wasallam.
In view of his unique status of being that gathering point, the Noble Messenger of Allah, Sallallahu alaihi Wasallam, said:--
"I AM THE LEADER OF THE CHILDREN OF ADAM, AND THIS IS WITHOUT
BOASTING." [Tirmidhi, Muslim, Abu Dawud].
And if we view each point of the circle in itself, we see that each of them can be a connecting point, giving us some sense of equality. Here, you may quote the Prophet, peace be upon him, where he said:--
"IT IS NOT FIT TO ELEVATE ME ABOVE MY BROTHER, YUNUS IBN MATTA." [Bukhari, Tabarani, Ibn Majah]. And in the Holy Qur'an, we have read it where it says:--
"WE DO NOT DISCRIMINATE BETWEEN ANY OF HIS MESSENGERS." (2:285)...
because discrimination is a hole in the COMPLETENESS of the Circle of Prophethood.
