The Personal Appearance of Muhammed (SAW)
He was of medium build, physically strong, with a large head and wide shoulders and chest. He had a sun tanned, fair complexion, his eyes were large and black with a fine, arched brow and long thick eye lashes. He had a beard up to his chest and a trimmed moustache. Over his back between his shoulders was a dark brown patch, one of the signs of his Prophet hood. He used to wear a silver ring with 'Muhammed Rasullallah' written on it (Muhammed Messenger of Allah). He was always absolutely clean in body and clothes he dressed humbly-he only wore expensive clothing when they were presented to him as a gift from other nation leaders as a sign of appreciation. He loved to wear perfumes and he ate little, slept little and spoke little and never of himself. He walked briskly and his companions would find it difficult to keep up with him. His presence and gait were dignified and imposing, truthful, sincere and unselfish - caring for others above himself. He was intelligent and with a good memory.
The foretelling of Prophet Muhammed (SAW) in Other Scriptures
Wa innahu lafee zuburil awwaleen - And verily it is in the scriptures of former people's - TMQ (26:196)
There have been scriptures before the Holy Qur'an and in them there is mention of the Prophet's arrival. They include the Injeel (Bible), Torah (Talmud), Vedas, Pumas/Purana and Parsi scriptures. There is even mention of the Prophet Muhammed by Guatama Buddha relying to one of his students Ananda.
New and Old Testament
Torah, Book of Deuteronomy (18:15) - The Lord your God will raise up a Prophet like thee (Musa/Moses, RA) from among your brethren, and I will put My words in his mouth; and he shall speak unto them all that I command. * NB
Gospel of John (14:16) - And He will give you another Counselor with you forever
(14:26) - . . . he will teach you everything I (Jesus/Isa) have said to you
(15:26) -He will testify about me
(16:8) - When he comes, he will convict the world of guilt in regard of sin, righteousness and judgment
(16:13) - But, when he, the Spirit of Truth comes, he will guide you all into all truth. He will not speak of his own; he will speak only what he hears and he will tell you what is yet to come (16:14) He will bring glory to me by taking what is mine and making it known to you
There is mention of a great personality by the name of Vada Mehat and Ahmedir. These are Sanskrit words which are similar to, if not the trans literal equivalent of Ahmed which is the same as Muhammed. The specific mention is found in the Bhagavad Gita, Bharishya Purana/Puma. " Just then an illiterate man with the epithet teacher, Muhammed by name, along with companions . . . that Great Deva, the denizen of Arabia . . . O denizen of Arabia and Lord of the Holies to thee is my adoration. O thou who has found many ways to destroy the devils of the world! O pure one from among the illiterates. O sinless one, the Spirit of Truth and absolute master, to thee is my adoration. Accept me at they feet." Parv 3 Khand 3, Adhey 3 Shelok 3-8)
Guatama Buddha said addressing one of his disciples Ananda question of who would teach them after he passed away - " I am neither the first Buddha, nor the last". This can be found in the Ceylon text.
Parsi Scriptures (Persian religion)
There is clear prophecy about the arrival of Muhammed (SAW) in Dasatir No.14 - it mentions a man born in Arabia who would conquer Persia (a superpower of the time of the Prophet Muhammed (SAW)) and destroy the idols in the house (the Ka'ba in Makkah). ". . . wise men of Persia and others will join his followers". All this did happen with the arrival of Muhammed (SAW) and Persia is now Iran, a Muslim country.
* NB - There are prophecies about Muhammed and these are borne out as truthful. There is no doubt that Allah had informed people of other scriptures about the Prophet Muhammed (SAW) as the Spirit of Truth. In the Injeel (Bible) Old Testament many Christians argue that the Book of Deuteronomy (18:15) is referring to the Prophet Isa (Jesus) but it states "like me" and the Prophet Muhammed was more like the Prophet Musa (Moses) (AS) than Jesus (AS) was. The facts are that both Muhammed (SAW) and Musa (AS) both married and had children. They both died natural deaths and their graves are on earth. They both were leaders and they both had a father and mother whilst Isa (Jesus) only had a natural mother. His birth was a miracle. Another fact is that Muhammed and Moses brought new laws and Jesus did not - Matthew (5:17-18).
