The supreme perfection of the Holy Prophet (Sallallahu alaihi wa sallam) is that He saw His Lord Almighty.
Zubdatul Muhadditheen, Muhaddith-e-Deccan Abul Hasanaat Hadhrat Syed Abdullah Shah Naqshbandi Mujaddidi Qadri (May Allah Ta'ala shower His mercy on him) says about the grandeur of the radiance of the Holy Prophet (Sallallahu alaihi wa sallam):
Translation: There were 70,000 angels on the right and 70,000 angels on the left. Each one of them had a torch of the Noor of the ‘Arsh. In spite of all this, the radiance of the blessed face of the Holy Prophet (Sallallahu alaihi wa sallam) was a class apart. It was ordered thus: O Jibreel! There are thousands of veils on the face of my Beloved. Even then His radiance is such. Okay, raise just 1 veil. The moment 1 veil was raised that the thousands of torches paled before the Noor of the Holy Prophet (Sallallahu alaihi wa sallam).
In the journey of Taif, stones were rained upon the Holy Prophet (Sallallahu alaihi wa sallam) so much so that His blessed feet had bled.
Before beginning Meraj, Jibreel (May peace be upon him) opened the heart of the Holy Prophet (Sallallahu alaihi wa sallam), took out the blessed heart of the Holy Prophet (Sallallahu alaihi wa sallam) and washed it thrice with the water of Zam Zam. No book of Hadith, Tafseer, history or Sirah mentions that even a drop of blood emerged when his blessed chest was opened.
The Holy Prophet (Sallallahu alaihi wa sallam) is both Noor and Bashar (i.e. human being). Bleeding when injured is a token of being human and not bleeding is a token of being Noor. Not bleeding even a single drop of blood when His chest was opened is a miracle of His Bashariyyah and bleeding when hurt is a miracle of His Nooraniyyah. Thus, the Holy Prophet (Sallallahu alaihi wa sallam) is peerless both as Noor and as a Bashar.
In the 12th year after the declaration of Prophethood, the night after the 26th of Rajab, Allah Ta'ala granted the Holy Prophet (Sallallahu alaihi wa sallam) the heavenly journey of Meraj.
