Several hadiths state that the Prophet MOHAMMAD (pbuh) was created from light of Allah [1,2]. But here is a point that must be considered. The meaning of this kind of ahadith refers to light truth of holy prophet and don't speak of physical existence of his Majesty.
On the other hand, in the level of material and physical presence, The Prophet (pbuh) was born like other humans, and has lived like others, though his live was, is and will be the best paradigm of religious living.
So there ares two truths or two facts about the Prophet (pbuh).
