It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him), who reports from the Prophet (peace and blessings of Allah be upon him) that he was asked: "Which deed is the best among deeds?" The Prophet (peace be upon him) replied: "To have faith in Allah, and to strive (do jihad) in His way." It was asked: "Which slave is best to set free?" The Prophet (peace be upon him) replied: "The one whose price is highest and who is most valued by his owners." The questioner asked: "If I am not able to do some of these deeds, then what do you instruct me to do?" The Prophet (peace be upon him) replied: "Then help someone who is working or do work for someone who is unskilled or incapable." The questioner asked: "If I become too weak to do even this?" The Prophet (peace be upon him) replied: "Then restrain yourself from harming people (and do not cause them trouble); this will be a charity from you upon yourself."
