Ronaldo travelled to Iran with Al-Nassr back in September when they faced Persepolis in the group stage of the Asian Champions League.
During the visit, the Portuguese superstar met Iranian painter painter Fatima Hamimi, with the artist gifting him some paintings.
Hamimi, who is reportedly 85 per cent paralysed, was thrilled to meet Ronaldo, with the 38-year-old greeting her by giving her a hug and kissing her on the cheek.
The picture of them meeting has angered Iranian lawyers who have reported him for committing adultery, according to Mundo Deportivo.
In Iranian law, touching a woman who isn't your wife is the equivalent to adultery.

As a result, Sharq Emroz, a TV station in the country, say the Iranian justice system has already sentenced the football icon to 99 lashes the next time he travels to the country.
Ronaldo is not due to travel to Iran given that Al-Nassr have already faced Persepolis away in the Asian Champions League, however he could be arrested if he travels there in a later round or on a personal visit.
Should he be arrested, Ronaldo could be forced to take his punishment of 99 lashes, however the sentence could be forgiven by a judge if the 'acts are not punishable or Ronaldo shows remorse'.
