Make expiation through fasting , giving in charity , offering sacrifices . Help those who are less fortunate than you . Do good deeds .

This hadith is about the Prophet's advice to Ka'b bin 'Ujra when he came to him with a lice problem. The Prophet told him that he should make expiation in the form of fasting, giving in charity, or offering a sacrifice. Fasting should be done for three days and the Nusuk or sacrifice should be a sheep while the Sadaqa or charity should be given to six poor persons. This hadith teaches us that we can make up for our mistakes and wrongdoings by doing good deeds such as fasting, giving in charity and offering sacrifices. It also teaches us that we must help those who are less fortunate than us by providing them with financial assistance whenever possible.
