At Religious class

Today at religious class, my friend didn't come and quite lonely but it was fun learning new things as we get a lot of knowledge. My teacher taught me like how to pray together and if we are late for prayer, we can still continued and joined them but still need to pray again because we just continue where they stop if u know what i meant by. My teacher showed us a video about an accident where 4 or5 people never pray and because of that they died in accident.. It was quite scary as we all know that we might die any time without knowing. So i learned from my teacher that never leave your prayer because it is sinful...
