Be honest and truthful about one's identity

This hadith from Prophet Muhammad ﷺ warns us against making false claims about our identity. He said that if someone knowingly claims to be the son of someone other than their real father, they are disbelieving in Allah and will face punishment in the afterlife. Similarly, if someone falsely claims to belong to a certain group or people, they too will face consequences for their actions. This hadith teaches us that we should always be honest and truthful about who we are and where we come from, as lying is a major sin in Islam. We must also remember that Allah knows all our secrets and lies, so it is important for us to stay away from falsehoods at all times.
