Saud bin Nasser Al Shahry claims trafficking his son is the only option to continue providing for his wife and daughter.
He says he is willing to go to court to complete the sale, the only condition of which is to know which city the buyer lives in.
It is not clear whether his actions are merely a publicity stunt or, if genuine, whether he would be able to carry out the sale without redress.
Human trafficking is an offence in Saudi Arabia, but the country does not comply with minimum international standards, according to the U.S. Department of State.
In recent reports, quoted in Venture Beat, it said the Saudi government 'continues to lack adequate anti-trafficking laws, and, despite evidence of widespread trafficking abuses, did not report any criminal prosecutions, convictions or prison sentences for trafficking crimes committed against foreign domestic workers.'
Facebook is also unlikely to allow such a sale through its website.
According to its Statement of Rights and Responsibilities, users 'will not post content or take any action on Facebook that infringes or violates someone else’s rights or otherwise violates the law.'
Around half of all Saudi children face domestic violence or some kind of abuse, it is claimed by a Saudi Arabian human rights group, The National Society for Human Rights.
