Men's use of gold, gold dust, the benefits of gold...
Gold Usage
Due to our religious beliefs, men do not wear gold. It is said the reason for this is to appear away from ostentation and modest. However, our ancestors knew science and knowledge much better than we do. For example, they would not give goat's milk to babies under 1 year old "so they wouldn't get the goat's stubbornness". Now it is being examined scientifically and it is said that goat's milk is low in vitamin B12; this causes restlessness and developmental problems.
In a study examining the use of gold scientifically and published on the cover of the German Stern Magazine in the 1980s, it was stated "Islam is Right". ("Islam Hat Recht" — I could not find this information on the internet, but my memory is strong; the title was like that. Those who wish to research can look at the Stern Magazine archives.)
