Walid Husayin is a person who has been in the news because of some things he wrote on social media.
He wrote some things that some people didn't like, and they thought were disrespectful to their religion. This upset them and they wanted something done about it.
So the government got involved and arrested Walid Husayin for what he wrote. They said it was against the law to say those things.
Some people think this is not fair because everyone should have the right to express their opinions, even if others don't agree with them. But other people believe that there should be limits to what you can say, especially if it might hurt other people's feelings or be offensive to them.
So that's what happened to Walid Husayin - he got arrested for what he wrote on social media.
