This story has been all over Arabic language media over the past week.
According to the story, a Jewish embryologist at the "Albert Einstein Institute" named Robert Gillham converted to Islam after discovering that a man's "imprint" remains with a woman he's slept with for three months afterwards.
The story says that Gillham tested women for the existence of these "imprints" and discovered that many American women had imprints from multiple men, showing that they were promiscuous. He tested his wife and found out that she also had sex with other men, and in fact one of his three children was not his.
But Muslim women that he tested were all faithful, according to the story.
Since Islam decrees a three-month waiting period after divorce in order to ensure that any subsequent child has clear parentage, his purported discovery of this three-month "imprint" proves that the Koran contains all of modern science - and therefore he converted to Islam.
I could find no record of any embryologist named Robert Gillham nor any doctor with that name who worked at any institution named Einstein.
The story was first told by Dr. Abdel Basset Mohamed al-Sayed, an Egyptian professor, and has been published in numerous Arabic media since then.
The irony is that the 90 day waiting period after divorce in Islam, which supposedly shows how well the Koran knows science, comes from...Judaism!
