Be generous in helping those who are in need of help; Be willing to make sacrifices for the sake of others; Use blessings wisely; Do not take blessings for granted .

This hadith is about the advice given by Allah's Messenger (ﷺ) to Ka'b bin 'Ujra when he was troubled by lice. The Prophet asked him if his lice had been troubling him and then advised him to shave his head and either fast three days or feed six poor persons or slaughter one sheep as a sacrifice. This hadith teaches us that we should be generous in helping those who are in need of help and that we should be willing to make sacrifices for the sake of others. It also teaches us that we should not take our blessings for granted but instead use them wisely in order to help those who are less fortunate than us.
