Unfortunately the article was written in Arabic; however I will do my best to translate the essence of the article in English.
The article talks about Mohammad's spit, sweat, blood, defecation, urine, and semen.
Spit: Of course as we all may have known, that Mohammad being the prophet of God, therefore his mouth does not contain any sort of germs, or any kind of impurities.
It is mentioned in stories told about him through out his life that his spit was used as means of medicine to cure illnesses and severed body parts.
In one of those stories, a woman came to Mohammad with her son and told him that her son is rebellious and possessed by a demon, so the Mohammad opened the boy's mouth and spat in it, and repeated this sentence three times :"Be gone Enemy of God, I'm the prophet of Allah".
In another story, Mohammad was drinking water, then a man came to him and begged Mohammad to spit in that drink so that he can offer it to his father, may it will purify his heart. So did Mohammad, the man went to his father with the cup of spit in his hand and offered it to his father, were the father asked his son, about the contents of the cup. And the son replied, it contains the spit of Mohammad and it will purify your heart. The father replied: "I rather drink your mother's urine, for it is more pure than that spit".
Sweat: It appears that Mohammad didn't produce sweat like the sweat that humans produced, as we've been told, but his sweat was a holly sweat, that smelled good.
In one story Mohammad was spending the night at Anas's home, while he was sleeping he started to sweat, when Anas's Mother came to him while he was a sleep, and started drying his sweat with a piece of cloth and in to a small bucket. While this was happening, Mohammad suddenly woke up, and asked Anas's mother what she was doing. She answered: "it's so we can use it as a perfume"
Holly Shit: Mohammad was also famous for his Holly Shit, stories about him tell the significance of his digestive system, and about the sweet aroma of his Holly Shit, not only that, it also says that when ever Mohammad went to take a crap, the earth would open up under his ass, and swallow his shit. As you can tell, it's amazing.
what is more amazing, is that most Muslims all over the world are willing to believe all this, but they still don't believe that man has landed on the moon. it is the ignorance that made religious people believe in myths and rubbish, and reject science with all the evidence that it has provided.
