I'm most worried about the future, is; if you leave Prayer let alone lose the Aqidah of Islamic religious beliefs. Because, at this time there are many mental crises of faith on this earth. There are many bad things to be proud of, the human mindset has changed from being civilized. Nature is no longer friendly because human activities cause damage. Be afraid of the creator, namely Allah. No human is immortal, rest assured about life after death. At that time the responsibility will be calculated. The world is only temporary, the responsibility of living at this time will be faced alone. Because, Obedient Angels can not be negotiated. Regret later cannot be changed after we are already in the grave, during our lifetime we change the way of life. In order to do good deeds of worship, leave bad things behind. Actually humans are in a state of loss except those who believe. Friends of the doomsday is near, riots all over the earth's surface after that. Everything will be destroyed including the solar system.
