Narrated Abu Huraira: The Prophet ﷺ said, "(Religious) knowledge will be taken away (by the death of religious scholars) ignorance (in religion) and afflictions will appear; and Harj will increase". It was asked, "What is Harj, O Allah's Messenger ﷺ?" He replied by beckoning with his hand indicating "killing".
The Prophet ﷺ also reminds us that we should not take our religion lightly or neglect it as this could lead to dangerous consequences for ourselves and those around us. We must make sure that we are constantly learning more about Islam so that we can protect ourselves from any harm or danger caused by ignorance or violence in society.
