His body
The body of the Holy Prophet (Sallallahu alaihi wa sallam) was matchless. It was very fine and exquisite. The fragrance which emanated from His body would not only make the surroundings fragrant, but would revivify the very soul of all those who were present with Him (Sallallahu alaihi wa sallam).
His complexion is white mixed with red, as if fashioned out of silver.
His person
Hadhrat Ali (May Allah be well pleased with him) describes the person of the Holy Prophet (Sallallahu alaihi wa sallam) in these words:
Translation: The Holy Prophet (Sallallahu alaihi wa sallam) is neither too tall nor too short, He is of a moderate height, (but it is a miracle of His person that in spite of being of medium-stature, whenever He would walk along with a tall person, He would be taller than the tall person). His hair are neither curled with rings nor lank, but are curved. His hair were sometimes till the earlobes, sometimes till half way to the neck, and when they went beyond it, till the end of His neck. They never went beyond this). He is not very fat and neither is His face round. His face is a bit round, fair and its complexion is white mixed with red. The black of His eyes is a deep black and their white is a clear white. His eyelashes are long. His body is clean of hair. There is a line of hair between His chest and His navel. His palms and feet are muscular. When He would walk, He would raise His feet with effort, as if He was descending from a higher place to a lower one. Whenever He would pay attention to somebody, He would turn with His whole body towards them. Between His shoulders is the seal of Prophethood and He is the Seal of all Prophets. He is the most generous, the most truthful, the most gentle and would treat others in the best manner. Somebody who saw Him suddenly would be awed by Him and the one who would keep in mind His status and meet Him would be captivated. Those who describe His attributes say: I have never seen anybody like Him either before Him or after him. (Shamail Tirmidhi, Pg No: 1)
Allah Ta’ala has kept His Beloved and Pure Prophet (Sallallahu alaihi wa sallam) free from all kinds of blemishes and flaws - be them external or internal. His body was fashioned out of Noor. No fly ever sat on His Person, nor on His clothes. Imam Zurqani says: The Holy Prophet (Sallallahu alaihi wa sallam) is Noor. Flies, lice, etc. come because of any dirtiness and foul odor. The Holy Prophet (Sallallahu alaihi wa sallam) is pure from any kind of blemish and His body is fragrant.
Allah Ta’ala sent His beloved Prophet (Sallallahu alaihi wa sallam) with radiance. There is a mention of this in the Holy Quran also.
Lo! There has come to you a Noor the Prophet) and a lucid book‑Surah Maida (5:15)
The Exegetes (Mufassirin) have explained this verse. The “Noor” mentioned here is the Holy Prophet (Sallallahu alaihi wa sallam) and the book is the Holy Quran, as given in Tafseer Jalalyn, Baydhawi, Ma’alim ut Tanzeel, Tafseer Kabir, etc.
Musnad e Ahmad, Tabarani and Baihaqi have a Hadith on the authority of Hadhrat Abu Umama (May Allah be well pleased with him):
Translation of Hadith: The Holy Prophet (Sallallahu alaihi wa sallam) said: I am the prayer of my forefather Ibrahim (Peace be upon him) and the glad tiding of Hadhrat Isa (Peace be upon him). When I was in her womb, my mother saw that a radiance issued forth from her womb and even the mansions of Syria were lighted up with it.(Khasais Kubra, Vol. 1, Pg No: 46)
