Hazrat Abu Dharr Ghifari narrates that I asked: O Messenger of Allah (peace and blessings be upon him)! Which deed is the best? He (peace and blessings be upon him) said: To have faith in Allah, and to strive in His path. I asked: Which slave is the best? He (peace and blessings be upon him) said: The one who treats his family well and whose price is higher. I asked: What if I am not able to do that? He (peace and blessings be upon him) said: Then help someone who is working, or treat an unwise person kindly. I said: What if I am not able to do even that? He (peace and blessings be upon him) said: Then keep people safe from your evil, for this is a charity that you do for yourself.
