Superstitions in Muslim societies are ideas or beliefs about things that some people think can bring good luck or bad luck. For example, some people think that it is unlucky to have a cat cross your path. Other people think it is lucky to have a fish as a pet. It's important to remember that not all muslims believe in superstitions - some do and some don't! But if you meet someone who does, it's a good idea to be mindful and respectful of their beliefs.
