Will tatoo be a problem in Saudi

My brother is planning to go to Saudi for job . He is a Muslim. He had a tattoo on his chest. Will that be a problem for rejecting his visa.

@Amigo S17 of course it shouldn't be a problem with the tattoo as alot of young saudi people started to get tattoo nowadays, I myself have one and I've been here for 3 years, goodluck with his relocation
