Take responsibility for your own actions instead of blaming your parents or ancestors.

This hadith is about how a person's sins should not be passed down to their children. It was narrated from Tariq and Muharibi that a man said to the Prophet Muhammad, "O Messenger of Allah, these are Banu Tha'labah who killed so and so during the Jahiliyyah [pre-Islamic period]: avenger us!" The Prophet raised his arms until the whiteness of his armpits could be seen and said "No mother's sin can affect her child," twice. This hadith teaches us that no matter what wrongdoings or sins our parents have committed, we should not be punished for them. We are responsible for our own actions and must take responsibility for them instead of blaming our parents or ancestors. It also teaches us that justice is important; even if someone has done something wrong in the past, they cannot be punished for it now because it would not be fair or just.
