Shave your head ; Sacrifice a goat ; Observe fasts for 3 days ; Give 3 sits of dates .

This hadith is about the importance of atonement through sacrifice and charity. The Prophet Muhammad ﷺ passed by Ka'b b. Ujra who was troubled by vermins on his head, so the Prophet ﷺ advised him to shave his head and either sacrifice a goat, observe fasts for three days, or give three sits of dates to feed six needy persons as a form of atonement. This hadith teaches us that we should always strive to make up for our wrongdoings through acts of charity and kindness towards others in order to seek forgiveness from Allah SWT. It also emphasizes the importance of helping those in need by providing them with food or other necessities they may require in order to live comfortably. Furthermore, it encourages us all to be mindful when making mistakes so that we can take steps towards rectifying them before it's too late.
