Give charity generously; Help those who are less fortunate than yourself; Cleanse your heart and soul through acts of kindness; Be compassionate towards others.

In this hadith, Abdullah ibn al-Arqam uses the metaphor of a man washing his lower garment and its folds to explain that charity is like people washing away their own impurities. He was trying to emphasize how important it is for people to give charity in order to cleanse themselves from any wrongdoings or sins they may have committed. This hadith teaches us that giving charity can help us become better Muslims by purifying our hearts and souls from any negative thoughts or actions we may have done in the past. It also encourages us to be generous with our wealth and resources so we can help those who are less fortunate than ourselves.
