Everything that hurts a believer is a calamity. Tests are like gold. You test gold in fire to test if its real, test its substance. That is the true nature of calamities- to test you. Allah knows your state before and after the test. Your test is for you to learn and others around you. Most of our actions are reactions- control your reactions!
