Respect your parents & obey them whenever possible; Be honest & truthful in your dealings; Avoid associating anyone with Allah; Avoid giving false testimony/utterances .

This hadith is about the warning given by Prophet Muhammad ﷺ regarding grave sins. He said that the most grievous of all grave sins are associating anyone with Allah, disobeying one's parents, giving false testimony and making false utterances. These are serious offenses and should be avoided at all costs as they can lead to severe consequences in this life and in the hereafter. It is important for us to remember that we must always strive to be truthful and honest in our dealings with others so that we can stay away from these grave sins. We should also respect our parents and obey them whenever possible as it is a sign of gratitude for their sacrifices for us throughout our lives.
