It is narrated from Hazrat Abu Dharr (may Allah be pleased with him) that he heard the Noble Prophet (peace and blessings be upon him) say: Fasting in the month of patience (Ramadan) and fasting three days in every month is like fasting all the time, and it removes malice from the chest. I asked, "What is meant by malice in the chest?" He replied, "Satanic filth."
