ISIS militants are teaching the kidnapped children with Sharia law and they are also forced to pray five times a day.Human Rights Watch said two of the boys who escaped told the media that ISIL was forcing them to undergo lessons in sharia and jihadist ideology, and that those who misbehaved were beaten. The group said several of the boys' fathers had received regular phone calls from their sons, though others said they had not had any contact.There have been fears that IS could train the boys tofight, though there was no evidence of that yet.
